Put you glasses back on and read what I said. I was commenting on your quote that 24# injectors aren't needed on ANY 306 based NA combination. That's a might broad statement on your part....one that's wrong. I maxed 19# injectors out on one of my combinations long ago. So much so, that even 24# were marginal at best. That was with a 306ci motor with unported P-heads and an E303 cam. That car went 11.97 with a T5 at 3200#.

I've tuned more than 250 cars since I opened the shop 18-months ago. I think my experience far outweighs yours. I think I've seen enough to stand by my original statement that SD (Ford EEC versions) isn't as accomodating as MAF-based (Ford EEC versions) is. Unless you've got Mike Wesley in your back pocket, you're going to be pretty much out of luck in terms of tuning the SD system for changes such as cams, heads, blowers, etc. Slap a FAST SD system on it an you've got a different situation...primarily because FAST has carried the programming and user interface onward. You won't find this is the case for EEC-IV SD systems. Autologic is almost non-existent any more, SCT has very few SD box codes available, and Diablo doesn't handle it at all (to the best of my knowledge). So if PDR has big plans on down the road, a MAS conversion should be in those plans somewhere. 'nuff said.
