Default Need help guys!!

We installed a BF 2.93 and idlers today along with NGK TR6's gapped at .025. Im getting dyno tuned on Tuesday and I just took the car for a short cruise (did NOT get into boost) and its bucking at a cruising idle and under deceleration. It can be felt as well as I can hear the exhaust burble when it happens. Any thoughts, Bobs out of town and I need to get this thing right by Tuesday morning.

Is the air intake stock/ after market, which one, did you remove for any reason and put back on?

Do you have the stock tune in or a base tune in?

Did you just put in on today, or was it already on there before the pulley change?

What you changed should have had no effect on your car if you are not on boost. My suggestion if you have time is put plugs back to normal gapping and see if that makes a difference for now.

Try gapping them at 28-30 and see if that helps.

Gap should be .32-.38. Mine were gapped at .35 and ran smooth as glass. Tuned by DynotuneMP.com

Will do, hoping for some good ones considering it put down 410 rwhp with just a cold air and exhaust on the stock tune.
