Soo today I ran my friends 2013 Si coupe, his mods are CAI and fullrace catback and reflash....my mods: skunk 2 CAI , p2r tbs, full race 3" catless downpipe, invidia n1 catback, flashpro with vitviper tune. Now the outcome was pretty tragic. We did a 30 roll and my god he just rocketed out in front of me and pulled like a car and a half. Just didn't add up. My guess is that my car is still running sloppy because vit just started tunning it (only on calibration 17). But still I would think my car would still be faster? Any thoughts?
