My buddy owns a 1996 M3 with the following mods: conforti chip, full intake, cat back exhaust, clutch fan delete, traction control delete (before mods 240HP, 238TQ)
My car is an 03' WRX wagon w/ COBB stg1 93 oct, blitz nur spec cat back, Tein springs and a short throw.
The first time we ran was before i got my stg 1, we ran from a 2nd gear roll ~ 35 mph to 100 (i try to avoid grenading my clutch). he ended up having about 2 car lengths on me by the time we hit 80 then i let off cuz we were approaching a car so by 100 it prob would have been 2.5-3 car lengths.
Fast forward to tonight about a month later and i just installed my COBB stg1 about a week ago. same road and conditions as before, and i was dead even with him this time at 100 actually even pulled ahead for a second or two in 3rd gear.
Super happy with my COBB AP, can't WAIT to get my dp/up and switch to stg2
