I have a 2004 Wrx with the following: ej257 sti block, wrx heads, Atp Garret gt3076r turbo, deastchwerks 850cc injectors, 1 step colrder plugs, hallman pro mbc, turboxsfmic, perrin big maf intake, perrin 3" turbo inlet, forge recirculated bpv.
The car was tuned at Pure Tuning in Toledo, Oh. I have the receipt from the rpevious owner for it.
-Stumbly idle, jumps and falls when cold, and when its warm it sounds like its cammed.
-Very stumbly and jolty when shifting between gears, bucks the whole car.
-Difficult to rev the engine, sounds/feels like it chokes fuel or something when revving and falls hard.
-Revs fall hard when coming to a stop, has actually stalled quite a few times.
Seems great in boost, boost is 20psi (has failsafe in the tune at 22psi). Previous owner said it made 351whp and 331trq, i ran a 12.7@109 as it sits.
