I am going to swithc to a EFI unit and wanted some feedback on Edlebrock vs. Holley EFI. I am running a Edlebrock Performer series Carb and Intake now. I like Edlebrock products. But I want to make sure for $2000.00 I get the best EFI out there......Also any thoughts on the Holley Tunnel Ram EFI??? Thanks.......

4 years ago I installed Holleys ProJection 4Di, finally pulled that crap off and reinstalled the Q-jet, First 3 days ran great,,,, then the thing wouldn't start unless you disconnected the dist from the PCM, start and run but no advance. Holley had me put relays and crap inline and patch it together, nothing worked, installed MSD small HEI and ran good. great gas milage, 67 Jeepster had about 9 MPG before and ended up with 17-19. Did ok for about 2 years, Then the milage went down hill. Noticed that the short term fuel adaptives kept climbing to the rich side, as far as they could, from idle to any type of cruise. Replaced O2 sensor, no change. reprogramed with all of their differnt fuel maps, no change,,, when it went into closed loop it would ramp up the fuel and run like crap. took meter readings from all sensors and they work properly, took same readings at pcm, same thing. Now I have to see if they can fix or SELL me a replacement PCM just so I can sell this POS EFI system. I am a drivability tech for a Chrysler dearler and have never had so many fits trying to get the bugs worked out of this system. But I guess that is why Chry has 1000's of man hours into programing for EFI stuff we run. Good luck. Aaron

Trick, I have the ProFlo installed on a 383, but since the truck is in total rework, it has not been fired up(about 3 weeks away). I have confidence it will be awesome. My bud has the holly system installed in a 347 Ford, utilizing the stock ford wiring etc but rechipped computer. It seems to work fine. Another much earlier thread was posted about three years of head aches with the Holly system that sort of follows the above post. I went with the 3507 system and the new Etech 200 heads. For 300 bucks more, you can go with the state of the art system!!! Also, have been impressed with Edelbrock tech support so far. Holly does not seem to have a good rep in that department.
