Karta, you're oversimplifying this and not thinking about it thoroughly. Most flashes remove fuel cut, so we have to first ensure he has a value there. Next, we have to determine IF it is fuel cut, because as I just said, it's VERY RARE to hit fuel cut at 4000rpm - simply not enough airflow to trigger fuel cut.

You've actually used someone else's EcuTek software? EcuFlash was just released recently and EcuTek has been around forever. I would think if you've used EcuTek, which is very expensive and would only be owned by major tuners, that you would know which was which. Strangeness, indeed.

ok ill re explain my self. before i had my intercooler installed i was hitting a peak of 28 psi in 4th. when i got the intercooler on i tryed to do a 4th gear pull and at around 4000 rpms max boost i hear a loud pop noise like the turbo maxed out and it backed off. so yes like i hit a brick wall. checked all piping and nothing was out of place. i can go any where under 28 psi but when i hit that mark it makes that noise. didnt do this b4 i had intercooler.

I had my car tuned by jestr for my meth.... all i did was add a front mount and now i cant stay at full boost in 4th gear which hits a higher psi then the first 3.

just stumps me because jester told me i was able to turn up the boost even more. i thought the max was about 30 psi so i was planning on turning it up to about 29.

I have done nothing with either program besides open and close stuff, never reflashed my own ECU. But, as my car was being tuned I watched very closely at what marco was doing. The first time he did the car he forgot to remove the fuel cut, and I went back after I tired race gas once, and he removed it by raising the values in one table. I really dont know much about tuning, especially something as complex as this. (SAFC's are easier) I could be oversimplifying it, but im pretty sure that when you change the table that alters boost cut, you just raise the tolerence to allow X ammount of airflow, it is entirely possible that it was raised to X ammount, yet with his new IC on this particular car, that ammount of X is now being reached quite early. Its a strech but entirely possible. Its also entirely possible that its something completly different. One thing is for sure, turbos dont just "max out" and "back off" like he is describing, he is talking about a fuel cut.

should i turn down the boost...? the point for the intercooler was for me to turn up the boost to cool the turbo more. not to turn the boost down.
