I'd want to be much higher in your power band when going through the traps. That and the weight is not helping ya.

What's your cam peak at?

Id be curious to see what it did unlocked as well.

None the less the car seems to be running well for the mods and weight. What is exactly done to the heads ?

Bet with a little weight drop and a good shock/coilover setup would drop your 60ft and et's like crazy!

Yea I'm gonna **** can the heavy *** bmr sway bar first, bet losing that will drop a 10th. As far as weight reduction I'm good with losing the radio, cd changer, speakers, amps, and all the crap behind the bumpers. I'd like to retain the backseat, cruise abs etc. I'm also going to a fast 102 and FTP 104 lid and we are going to tune it speed density.
