Been having issues with the car for a long time. If you want more details on it please check my post history as this has been going on for months. To cut to the chase.
The car is ko4 with supporting mods - intercooler (i know its next on the list). But has always felt a little bit down on power and I've had drivability problems like weird boost fluctuations on part and wide open throttle, my e30 tune runs god awful with the car bucking and having less power then 93oct for sure. both tunes have had many revision but the problems still remain so something hardware is at fault.
I've replaced
Maf
Map
coils
plugs
pcv
both fuel pumps
lots of leak test.
I will include a couple of logs of the cars current performance. What I would like to know is why the car seems to level out in maf readings until about 6k rpm. then the car does like hell but the fuel trim and pressure show the car dumping fuel.
im not very good at reading logs and don't know what's going on.
Fyi. The current tune does have a issue where the wgdc is to soft. the tuner was trying to tell me that the turbo is producing to much air for the engine to take in... ok then how do other people run this same setup and not have issues. (sorry the tuner for the 93 file has been a bit rude) but this type of spike and dip in the car has been around on other versions of the file and sometimes not at 6k+rpm
If more logs are wanted and of different things please ask.
