I have been researching EFI most of the winter and now it is past time to get going on this. I have talked with Alex Haxby several times and he has given me some good advice - thank you Alex. It seems that the Holley Terminator EFI is the best fit for my application. I would purchase through him, but he suggests I just go with Summit or Jegs.

Any suggestions on where to buy?

Always worth looking at these people

Do yourself a HUGE favor and buy the system form a SERVICING dealer, not the internet. What Jegs and Summit dont tell you is you need the dealer software to tune it. Most dealers what mess with a system they didnt sell and I understand why. They have to pay 2500 for the software and the up dates that come with.
I had one installed last year by MER Performance and Mark has adjusted on the system several times since then. I have a neighbor that bought one from Holley direct, thinking he could tune it..........wrong!

WTF are you babbling about? The Holley EFI sofware is FREE from their website. All you need to do is download the *FREE* software, plug the USB cable into the ECU and your laptop, and go tune.


Bill 3, I bought my Dominator setup from Blake Hughes at 417 Motorsports. He is usually able to beat the prices from Summit/Jegs/Speedway. In fact, most of the smaller shops will work with you on price.

I've tuned a lot of stock GM ECUs, some Megasquirt stuff......the Holley is the best I've messed with.

Thanks for the link.

I am here looking for recommendations before going through a retailer. I prefer to support the small guy with hopes of getting some support in return.

417 Motorsports is in my backyard.

I'd consider calling haxby

He said in his first post that Haxby told him to go elsewhere.

Sorry. Must've skimmed by that. It's called one word wide first post syndrome thanks to the ad.

I bought mine from Brian Orlandi 734- 586-0448
Orlandi Performance.
Set me up with everything I needed to do the install myself.
I did the sequential port injection setup.
I love it.
I have a 598 with a BIG solid roller cam and the engine idles without any problems in gear at 750 RPM

and his price was lower than I could have bought it from summit even with a coupon.

I bought mine from haxby but was installed and tuned by mark at Mer performance . Mark was not a dealer at that time but he is now. Give him a call . Jeff wurl
