About 7.3 Power Stroke :
The Powerstroke’s first engine is the 7.3L Powerstroke V8, and it is the Ford version of the Navistar T444E turbo-diesel V8. It is also known as ford Powerstroke. The 7.3 Powerstroke is a direct-injection engine and controlled electronically. The motor was introduced in 1994 and is a new engine with its stroke and bore dimensions common with the predecessor. It is the replacement for the 7.3-litre IDI V8. This engine’s block material is iron, and it uses diesel, HEUI direct injection, and a high-pressure oil pump water-cooled cooling system. It produces 130 to 475 hp and 350 to 1,050 lb.ft.

7.3 Powerstroke problems- What problems does the 7.3 Powerstroke have?
CPS – Camshaft Position Sensor:
The failure of the sensor would shut off the truck while driving or would create no start condition. Checking for tachometer movement in time of cranking the engine over is an easy way to diagnose the camshaft position sensor’s failure. The tachometer stays or doesn’t move to indicate the probably wrong CPS.
Fuel Bowl – Fuel filter/water separator:
The filter housing leaks fuel and creates cracks in the aluminium housing. The element of the 7.3 programmers creates heating inside the fuel bowl filter housing can be blowing a fuse, causing no start and sort out. The O-rings that locates on the fuel filter drain lever on the back of the fuel bowl assembly would leak and corrode.
Leaking Turbocharger Up-pipes:
The 7.3 tuner offers a fixed geometry turbocharger, and the pipes most commonly leak in the joint and can leak from many points—the engine power loss for exhaust gas temps-EGTs- to increase and the leaking of the up pipes.
EBPV Failure:
Old Exhaust Back Pressure Valves can stick on and open up in cold weather. The exhaust produces “jet engine” noise and can cause a loud whining.
Fraying or Melted electrical wiring:
Fraying, worn or melted wire causes different problems. It will cause misfires or rough starting. The under valve cover harness can stop communicating with the injectors of glow plugs.
Valvetrain:
The 7.3 Powerstroke tuner did not provide high seat pressure. It led to valve float at the high RPM’s and sometimes cause broken or bent pushrods. Shims and aftermarket springs help to solve this problem.
Injection Pressure Regulator – IPR:
A valve of the 7.3 high-pressure oil pump is an injection pressure regulator. It can get leaks in the O-ring, can stick or have a faulty connector.
Overheated Engine:
The engine can get overheated, and it is a common problem. It results from a rusted thermostat, a failed 7.3 radiator, running bad or wrong coolant, perforated or worn radiator and a broken engine cooling fan.
Fuel Bowl Heater:
The bottom of the fuel bowl contains the fuel bowl heater. It has a common problem, especially in old Powerstroke. It could blow the maxi-fuse ant the short or fail itself out.
Injection Control Pressure Sensor (ICPS):
The ICPS failure can make the diesel engine run rough. For the default settings of ICP and the going away of rough running, the PCM will use.
Looking for a chip? Let’s have a look on the TS performance chip 7.3 review
TS Performance is the king of the tuner industry. It has two major types of tuners that offer different features and performance. The first type is a single position Performance chip, and another one is a 6 position chip. Both chips enhance the drivability and mpg level at least 4-5 units. However, experienced drivers always prefer the ts6 tuners as it has to offer more horsepower and torque performance than the single one. The single one only offers 75HP, whereas the 6 position one offers up to 140 horsepower. To be mentioned, you have the control to adjust the settings in 6 different modes. 7.3 Powerstroke TS 6 position chip MPG will be increased just after the installation. Nevertheless, TS6 tuners will cost you more than a single one. But of course, it is worth the money.
The TS 6 tuners have the ability to adjust the settings without any pause in the middle of the road. You can easily switch your desired settings even while on the move. In the TS performance chip 7.3 review, I am going to assure you that it would not harm your engine rather, making it efficient and faster than ever. Besides, the installation process is a piece of cake. You wouldn’t need the help of an expert and cost extra bucks. The manufacturer will give you a step by step process manual in the time purchase. You can easily mount it on the dash following their simple instructions.
Ts6 chip 7.3 problems:
In the installation process, cleaning the connections on the computer is hard. Because the connection doesn’t be clear, the chips will not run right. If you don’t disconnect the batteries, it may cause damage to the very expensive PCM. If you get up to the 100 and 140 hp setting the shifting, it will not slam into gear, but the gear changes will kind of rough.

You will also download the engine calibration files and essential upgrades. There have plenty of upgrades that improve fuel efficiency and increase horsepower.
Fuel:
Select the best chip for 7.3 Powerstroke that can improve a vehicle’s combustion rate, causing it to cut its fuel consumption. It will do this by altering the time while the vehicle is delivering fuel.
Performance Levels:
All tuners and programmer modifies the transmission shift points, air or fuel mixture, and other vehicles’ performance settings. You should select the best tuner for 7.3 Powerstroke that offers high performance and high speed of your vehicle to unlock hidden torque, acceleration, horsepower and more.
Benefits of Tunes
Engine chip tuning customized or upgraded the car. The change in the software such as the ECU change, engine remap, or performance chip add creates a big difference in the vehicles’ function. These are-
Increase Horsepower and Torque:
The engine 7.3 Powerstroke tuner programmer may help to increase the intake of the vehicle for boosting its torque and horsepower. The ECU comes from the factory with conservative software settings also includes power settings. It helps the car be more stable in various conditions, but it also ensures that there is some power left behind. Chip tuning can change the timing and ratio of air or fuel to give the car extra torque and horsepower.
Increased Fuel Efficiency:
The 7.3 Powerstroke tuning increases the combustion rate of vehicles that causes cutting down their fuel economy. It will do this by altering the time while the vehicle delivers fuel. Engine chip tuning is used exclusively to get more power out of the vehicles, but recently, environmentalism and fuel efficiency modify it. A substantial improvement in fuel economy can be rendered with the right chip tuning.
Easy to install:
The installation of the tuners is simple and requires minimal labour cost. Universal diagnostic port makes it simple for plugging new engine chips into the current device without apart ECU. It reduces labor costs because the chip tuning can be done in a pro shop and more affordable even in a pro shop.
Read and Clear Trouble Codes:
OBD II of the vehicle generates the trouble codes while something goes wrong. Some tuners may be used for reading and even clearing trouble codes. The tuner provides these services free at home while the mechanics charge a hefty fee.
Interpret Data:
Tuners help to interpret the vehicle’s sensor data and can offer optimized tunes for a specific vehicle. Many of them monitor EFT temperatures, fuel/air ratio of the vehicle, and more.
Improved transmission shifts:
A tuner can help alter transmission shifts and get a transmission gear for shifting ups and downs that depends on the vehicles’ RPM. The shifting point affects the longevity, overall feel and performance of the engine.
Fit the Driving:
Chiptunes help ensure the driving place is appropriate for the vehicle and ensures that it is precisely to work at its best in these conditions.
