tst problems need info
 

iam having problems with my rail pressure feature.if i turn it up more then three the truck surges badly anybody else having this problems.i talked to tst and they were know help.thanks

Well what were the other settings on. Maybe that is all your CP3 can handle.

Have you put a better fuel pump on the truck yet? My truck starts surging on 3/2 on the TST. It's either the clutch slipping or I'm not getting enough fuel. My bet is that it's lack of fuel.

I have gdp fuel system.the other settings are tt03 and 5-2.I really dont think i am running fuel i can be just cursing at 65 and it does it.and i thought the stock cp3 was good to 550 -600.

If you have stock turbo, then I would suggest to switch to standard TST program with everything else the same and see what happens.

alright i will give that a try

TT03 is he11 on a stock turbo.
