Finally got around to getting a baseline and installing a pulley and tune. Not bad for $650 and a beer and a half worth of work.

Run 3- stock (almost, Airaid filter and resonator delete)
Run 6- with VMP 2.59 pulley and tune

Very nice numbers. Time for a timeslip.

Stay tuned... Ran a 12.58 stock on DRs in a 4,800 ft DA. Should end up pretty deep in the 11's I'm guessing.

I just pulled mine out after 6 months of it being in, my VMP pulley and tune was getting a check engine light with a P0420 code, thinking it had to go in for warranty work I reverted to stock cleared code. Put about 50 miles on it now stock and no engine light. Gonna keep it stock for a little while to be sure, its possible that the change in temp outside created a false light. Big difference in torque without the pulley and tune.

Joe if you wanna get it tuned precisely and the best your car can get, take it to the Shelby mod shop. They'll do great work for you. And their no more than anyone else.

po 420 is a catalytic efficiancy code, read off of the secondary o2 sensor, should have nothing to do with a pulley and tune, unless the pulley and tune had a effect of ruining the cat

Ive removed pulley and tune now, and since, I have not received the code. Im a little perplexed what to do!

Did the tune have the rear O2's turned off?

Call Justin. I bet it's something simple in the tune.
