Hey Mark, what problems are you having? I can try to help you if you want.
The bad news is, the XFI ECU has not had an update in about 8 years. The good news is, that update is proven to work well and has no issues that I am aware of. Quite a few guys still run that system with great success and no issues, including several contenders and the eventual winner of the National SS championship, and runner up for the National Stock championship.

It is also noteworthy that Comp/FAST/Edelbrock are very supportive of NHRA Sportsman racers and are known to be one of the quickest to pay contingency thanks to Billy Carroll.

If you are committed to changing to another system, I am not trying to change your mind, and the Holley HP or Dominator is a good system. I am just offering to help if you want it.

I?ve been out of the EFI category for a while because of a job change a few years ago, but I am back now. Let me know if you want to connect on the phone, email, etc. I?m confident I can help you.

Mark, can you message me your phone #? I got your message but I am not sure my replies are going through.

David is the man when it comes to the FAST system.

If you need any assistance with questions about the Holley I can help.

There are many good systems out there days and I heard FAST is making a return with new products. Should be good for everyone.

Hey Dave glad to hear you are back. After Max left couldn't get any help when I called in and basically hung up on me when I stumped them on a question. Is your email the same as your old one?
