Has anyone heard the car start up, then go low on the RPMs and then knock loudly before climbing RPMs and then being fine? Did it both on stock and aftermarket plugs. Tune fixed it eventually but just curious as to what you think caused it. I still have tip in issues to this day though. Runs great WOT.

- Start date
Never heard a knock on mine, was your car dyno tuned or email tuned?
e-mail
With emails you will probably need a couple of revisions to take care of the tip in issue. The best bet is to get her dyno tuned. i know it costs but a good dyno tune from a reputable tuner will get the most power and the best drivability!
can't remember if we did your tune or not, but we have had some nice revisions over the last few months on the drivability stuff on the Paxton cars
