Throw codes when I get on the gas with the TST on 3

[Van1]

Throw codes when I get on the gas with the TST cr on 3/3. It seems to only do it when I gun it for a bit. Is it because I am running out of fuel? I dont have a fuel psi gauge yet. It doesnt do it on 1/1, havent tried it on 2/2 and it seems to go away soon enough and it seems to run like normal. Just wondering if I have to get a pusher pump... isnt that what the fass and other systems are.

What year is your truck?

If it's a late '06 or '07, pull it off. Apparently there's some issue with the TST and the newer ECM programming. Something makes the injectors stick open too long over level 2.

If it's older, I have no idea. My TST only threw a code once on my '03, and it was due to me giving too much throttle when the truck was cold.

Running out of fuel will usually cause lots of smoke and maybe a loud POP!

I did that too on a dyno once or twice

Fuel psi does go pretty low with my tst on 3/3 but in never throws a code. What is the code that you are getting?

I have found with my 06' if i run the rail pressure on 3 or above it will set the check engine light! Turn it down to 2 and no more light! When the light is on ill do the 3 key thing and all it says is "done" and the light gose away after alittle bit. Its has done it every time i set the pressure above 2!

I can run 3/3 all day long with the rail pres set at 2 and no problems at all!

And some times ill turn it up to 5/2 with no problems.

I do need a fuel system bad!!!!!!!!!!!!!!!!!!
