Had the pleasure today to get to tune an 04 STi with the following mods... SZ55 FBTW, perrin modded injectors, AVCR, Perrin Big Maf, Helix downpipe, Magnaflow catback, Perrin inlet tube, APS DR725 intercooler, fuel pump, Topspeed Ecutek tune. The car came in on a trailer so I was unable to do a base pull because it wouldn't run.. so i droped in one of my base maps to get it to run. After i was done these are the numbers we got. I was hoping for a bit more but his exhaust has a 2 1/4" neck down as it is meant to bolt onto the stock downpipe non the less the car made great power. This car was a blast to drive... very smooth.
nice #'s Doug! after talking to Trey the other night...strongly considering on getting the stage 1 (forgot the exact name for it). car is still bone stock and i think this is a good step.
