I am from the Detroit area. I wanted to have my two 1250's tuned. I called around and found Ben at Chief engines also known as Precision Power Offshore in spring lake Michigan. I told him I had a pair of 1250's with the Holley EFI system and looking for a shop that could tune them. He told me he was a Holley expert. Ben convinced me to go there. I drove accross the state. I was there four days and three nights in a Hotel while I was waiting on Ben to get my engines running. He could not set the timing or set up the fuel map or timing map. He knows nothing. I sat there day after day watching him google the problem and check the Holley forum and call people. He told me my distributors were the problem. I drove three hours and spent $1000 on distributors that he cold not get to run either. He knows nothing about EFI. And even though he could not set the timing he charged me thousands of dollars. All together it cost me $3500 and I have nothing. My engines still do not run. Does anyone know of a good shop that dyno tunes 1250's with Holley EFI? Any help you can give me would be greatly appreciated. Thank you.

I think Brian Orlandi in Newport just down the road from you does Holley efi stuff....

Brian is the only one other than myself who I trust to work on my boat. Look up Orlandi Performance.

Thank you very much for your reply. Brian can not do reverse rotation. Again Thank you.

I'd get in touch with HaxbySpeed on here. He is the Holley EFI guru hear and has helped many out. He is in Vancouver, BC, but he might be able to lead you in the right direction.

I have a couple names if you want to get in touch with me. Tunes everyday from Bonnieville salt flats to the NHRA pro stock to other elite clients including marine apps and even OEM's.

By far at the top in the tuning world.

I have been talking to Mike over there for months. They are 60 engines to build. Have no time for more work. I know they could set the timing. LOL
