I asked Dave to help me dial in a 383 I had installed in my 1990 K2500. I changed out the injectors for 80# BB ones, and swapped the ECM for a '7427. I thought I had it running "ok", but knew it could be better. After ONE data log, Dave had my BLM's at 128 +/- 4! He also helped out a lot with the spark advance tables to get it running much more smoothly than I could get it. If you're considering having help getting your car or truck running to its full potential, Dave would be one of the first you should talk to!
