Dustin/Z1 folks:
Got a quick ?. As per my sig, I've already got the k&n drop ins and I've gotten an UpRev tune for all my current mods. I'm really interested in picking up a set of these PMTs from you guys but I want to confirm that I don't require a retune to be able to run these either on the street or on the track. (I'm looking to pick these up before the car goes to the track day at ZNationals). Will the a/f ratio still be safe w/o updated tune? I suspect a retune might pull a couple more ponies out of the car but my main concern for the immediate future is the safety of running them until I retune next year.
Thanks.
