Mine runs and drives. I used Summit's Holley bracket. After I opened it I discovered the instructions say it shouldn't work, but it does. I don't have cruise control yet, but I'll work on that after I finish rebuilding the original 700R4 - I have a junkyard 700R4 in it now.Has anyone made any progress on these builds? I bought the cheaper Summit Racing EFI system, and so far, it is identical to the FiTech system. I am curious how you guys plan on doing your factory cruise control, throttle cable, and TV cables?
Unless it’s a bad ECU or component out of the box, and EFI system will work well as long as ZERO preexisting conditions are present. Minor exhaust leaks, vacuum leaks, not enough GOOD grounds can’t hide from the EFI like it can be tolerated by a carb. Granted it feels like picking fly **** out of pepper but in this case you’ll taste it no matter how small it isI had NOTHING BUT TROUBLE with the sniper EFI & Hyperspark dizzy. I wired everything 110% & always had hard start issues as well as other issues. I had it dyno tuned at 2 different shops. The second made it a lot better, but still issues.. I gave up, swapped out to a carb, & been happy ever since! NO electronics to deal with!!! So I’m not sure what was the deal with my set up, but I hated it. Nothing but issues. The shop I deal with now installs fast, sniper ect all the time… they encounter that though all the time… some work amazing, others nothing BUT issues…
