How to tell if its reflashed

[smooth_ej20]

Well ive had my car for a little over a year now and it just occured to me that i have no idea what the previous owner might have done to it. I know he put in an UP and cat back but i was wondering if theres anyway i can tell if he got the ecu reflashed or not. Only thing i know for sure is that my boost peaks at 14.9~15 psi, but other than that i dont know if theres a way to tell. IF you guys have any ideas let me know.

If somebody reflashed it they would have turned the boost up, that turbo can handle 18.5-19lbs

i thought so but i wanted to make sure. DOnt want to hook up my UTEC and blow some shit up.

you def should have a professional tune your utech

well for now i was going to run TurboXS base maps for Stage 2. Once i upgrade other parts ill take it out to CFT.

He musta did something, that is pretty high.

Stock boost level is more like 13 lbs @ WOT in 3rd

Thats on a WRX - I believe the levels on the sti are higher

For a TD04? You'll only be blowing hot air. That turbo is max efficient around 16psi. The VF39 is good for around 19psi.

My apologies, I was under the asumption that we were talking about an STi, I am well aware of the boost efficency of both turbos

USF- even if i have a catless turbo back and up-pipe? i thought it might jump that high due to a little boost creep. If it is flashed, is there anything i can do to get it back to stock or am i up shit creek?

Ive got an uppipe and turboback, still have 13 or so lbs WOT 3rd

[smooth_ej20]

doesnt matter anyway. My UTEC will override any flash that could be there anyway so im not worried. Just have to decide when to get it tuned up
