mods & dyno numbers are in my signature. the tune is from Tune Time Performance in Toms River, NJ. i've changed a few things since then so a retune could pull out more power.

yea i did the same power with just a cai & catback on a mobile dyno jet. my numbers in my signature were on a Mustang Dyno, which is suppose to read roughly 13% lower than a DynoJet, i honestly think that's a bunch of BS. i found a local DynoJet that i'm going to jump on and see what it does.

i was on that setup, went to a 2.9, went to get my tune tweaked and was told the injectors were going static up top. so my tune really didn't change. i was told to either go back to a 3.0 or get better flowing 42s to be safe OR go 2.8/60s. i ended up getting a great deal on these Lucas 42s. i'm actually getting a retune very soon.
