Dennis,
I installed the Extender chip that I had on hand which was burned for the 60# mototron fuel injectors I have. The car seems to run better...it doesn't feel as sluggish anymore. The only true test is to go to the strip and flog it down the quartermile to see what happens. If I were you I would go with the PT61 from PTE as a replacement for your PT52, it probably is cheaper too!
I don't know when I will be able to find time to go to AK Raceway Park...I am buried with work and it is hard to break free with 3 young kids. I am going to try to get free once in August and once for Labor day...we will see, awfully hard to sell that to the wife...its like, "Honey, you watch the kids all day while I play." That will fly like a lead balloon! I am going to have to give her something, in order break free to play. Such is life with a non-automotive enthusiast wife.
Are you planning to come down to Anchorage anytime soon?
