Finally got some time to do some basic logging of my stage 2 cobb tune while waiting for my downpipe to arrive.

Mods are:

depo 3.5 IC
rocket science snorkel
stock airbox with capped KN and fswerks intake piping
magnaflow catback
steeda intake spacer (might have slight vacuum leak need to retighten the bolts) getting -10 vacuum at idle once warmed up with fluctuation to -10.25 and back again, not sure if normal


10.4 AFR at WOT 3rd and 4th

+4 correction on all cylinders

hitting 22psi

motor has 1500 miles on it, new longblock and turbo from ford was replaced before I bought the car.

you guys think a lot to be gained with a custom tune? car feels pretty strong, lost by a couple of cars to my friends fully bolted e30 ms3

I'd definitely check the bolts for any vacuum leak before doing a custom tune but yes you will notice a gain from a custom tune. I just got my ap for ran the cobb ots maps getting +4 corrects all cylinders and around 21-22 psi. My afr was around the same and from what ive read the cobb ots maps are ment to run rich for more of a safety reason. Youll just be losing more fuel but shouldn't hurt anything. I just got my first map from Justin at freektune and I can tell you it definitely feels better. The car doesn't rocket off in 1st, my corrections have been around +2 or so, still working on that. My afr is around 11.2 or so give or take a bit. And a fbo e30 ms3 will rape any non bt fost im pretty sure lol.

He should still have you I would imagine in HP, but if he only got you by a few cars then it might be close to even and I might be completely wrong.
