I figures out what my problem was. I was running stock injectors with Bosch Silbers spark plugs...and 10-15 pounds boost...One day I thought the bottome end was falling out of the motor when under load/boost. The car was missing and backfiring like crazy! So, I put in new fuel pumps and 30# injectors, cleaned everything out and fired her up and the missing/backfiring was even worse!

So this time I call Todd (TCD) and we figured out the problem...spark plugs. The good ole Bosch's did not have any electrodes! I completely disintegrated them! I put in some NGKs that are 2 stages colder, clicked the AFM 5 notches, and the issue is resolved.

Now I just need to spend some quality time getting it tuned in.

Hope this helps someone out there in DIY land.
