The first dyno graph was taken almost a year ago with the following power mods:
Cobb stage 2 93 octane(older map), Perrin IC hose, Snorkle elbow, K&N drop in filter, Helix downpipe, 2.5" borla catback. The ambient temp was 55 F or so.
2 days ago i went back in and have it dynoed again with the same exact mods aside from: Gutted uppipe, 3" borla hush catback, v1.30 cobb stage 2 93 octane map.
Can anyone explain to me why my car is running this rich after 4.5 grand?! It seems like it's pulling timing, but there is no audible pinging or anything. I got identical results in all 4 runs.
I just bought street tuner in hoping to lean out the mixure a little (11 A/F). can anyone shine some light on this issue?
Thank you so much ahead of time.
