Good day any and all advice and input is welcome: my son bought an 04 STI with a built motor, 10:1 compression, bored likely 30thousandth over, eagle connecting rods, C.P. pistons, AMR top mount intercooler, AMR big turbo, snow performance water/meth injection, 850cc Deautschworks injectors, warlboro fuel pump, likely some head work done as well, custom fab oil catch can, custom piping intake tube and filter. And likely more i am missing.
The issue is the car leans out real bad when Boost is being made, it has a turboxs piggyback ecu, my question is, should he keep the ecu set up the same and find a shop that can tune this set up, or disconnect and go all Cobb? Tuner shop in our city, feels more comfortable using the Cobb accessport set up and maps, will they be able to support these mods? And is my son better off with what he has or should he look at Cobb more seriously, I run a Cobb in my 04 STI as well but don?t have as built an engine as he does, let me know what you all think
So lean/knock is the issue, can?t really push the car or the error code is thrown any advice is appreciated
