Tst Codes And Problems

[COBRAJET]

I have installed and reinstalled the TST three times now and the device does nothing but make the truck run horrible and throw codes. Contrary to other posts I have had little help from TST. I called 5 times every hour starting at 9 eastern Friday and was not able to talk to someone. They were all too busy. Someone finally called back at 3 o'clock central time and said my boost was too high causing all the problems. The boost is bleeding now at 35 psi and the problem is the same if not worse. The truck sounds like a machine gun when you give it fuel and blows smoke horribly. It keeps throwing codes 0236 and 0336. I can take the device off and reset the codes and everything runs fine. When it is reinstalled the same codes and drivabilty issues come back. Any ideas..... CJ

did you remember NOT to hook up the ground on the cam/crank wire harness??



that will make you throw 0336 code - the other i have no idea... BUT (after you leave off the ground)... have you tried leaving the stock boost fitting in? so you only get 22-23 lbs?



so if that leaves the other code alone...



I feel your pain, the 5 amp fuse fix did NOT fix my code P2146- ??



but my truck runs great as opposed to yours

Mine came with a ground wire only on the injector harness. I tried that first... no good. I have tried at least 4 settings with the adjustable elbow..... they all produce a lot of smoke and a horrible exhaust note. The higher the fueling setpoint the worse it all gets... . CJ

Perhaps a swap-out might be in order... who knows with all these electrons floating around, maybe you got a wierd one

COBRAJET do you have a fuel pressure gauge and how long has it been since you changed your fuel filter?

 

[COBRAJET]

I do not have a fuel pressure guage. The filter was changed last weekend... . and at every 10K. I have been running a Quadzilla 140HP adjustable box for 55K miles without one problem. I reinstalled the Quad box this morning... no issues whatsoever. I put the TST back on... . lots of issues... CJ
