have a problem

I just got a new turbo put on the car with a new intercooler 800cc injectors and tuned it and ever since then i have thrown a few different codes.... one was p1235 wich i guess is overboost, the other was p1233 i think and that one said tps sensor high output and when that goes off the car barley moves and then one was a missfire code and the other was bank 1 system lean i think p0170 or something like that... none of these ever came up before all this.... has anyone experienced the tps sensor one cause that seemed a bit random and the lean one was kindof a shock because the a/f was around 11, in the high 10's....

How are you tuned? I'm not really keen on making modifications like yours without a good logging tool to tune with (sorry ECUFlash).

That pics horrible. Match your plug with Plug Chart and let us know. I just threw P1235 yesterday, and it came up as a MAF code. Overboost if I remember correctly is P1238.

Wow, ok. All my scanner said was 1235- air/fuel metering. My idle also stuck at 2k rpm right after it threw the code.

In addition to the over boost codes, it seems like you may have injector scaling/latency problems.

my rpms also jump usualy its after the car is already warmed up.. i start it up and the rpms hang low and jump up a bit.. if i dont rev it a bit it feels like its gnna die.. its weird if i got out for a drive a couple times a day it wil do it once of twice.. and sometimes it wont do it at all..
im still on the stock airbox and im also tuned!!!

is this normal on tuned cars too? cuz i know its normal on untuned evo x's =p

ohh yeah and im not throwing any codes.. and tuned by ecutek..
