Just finished installing my tuner kit with Jon Lund tune and Injector Dynamics 1000s today. Going to install the boost regulated BAP next weekend but had a couple questions. What are the best spark plugs to use with F/I? I know Paxton says to stay away from platinum's. Also I have had spark blowout under boost in a previous car and I am experiencing those symptoms at top end right now and was wondering if running out of fuel would have the same symptoms or would I just run lean?
Just realized I didn't gap my plugs to .35. Still at factory gap. Going to try that before ordering new plugs. From my understanding spark plug blowout occurs mostly with boosted applications where it can actually blow out the spark at high rpm/ boost which decreasing the plug gap takes care of.
Spark plug blow out is a older car problem I.e.. 04-08 f159s had 3 threads where the plug was in the head. Cases had happen where the plug and the threads was blew out the head, spark blow is blowing the fire out of the plug of that makes sense

Waiting on Aeroforce gauge/ boost adapter and I am running stock pulley but with an open cai type filter so it should be between 8-9 lbs of boost. Stock plugs should be fine as long as they aren't fouled and I re-gap them.

Are u running a wide band and what psi are u at. I would assume oem temp spark plugs would be okay as long as boost aint that high.

I bet your EGT's wouldn't mind a step colder plug. I'm coming from the suby/evo group though. It was common to run a step colder plug when running higher boost.
Well took care of the spark blow out issue but now the car is falling on its face right after a quick shift at WOT. Going to data log and send it to Jon Lund and see whats going on.
come to find out I was a little misinformed, the base tune I was sent was not meant for anything but cruising and idling until further adjustments were made. Waiting on the new tune file will keep updated.
