Hey Boys, I need an EFI setup to run my new setup. I have a 351, stock displacement, forged lower. It is 8.6 to 1, CHI alum heads and a vortech Ysi blower. I'm running a GT40 upper (pricemotorsports plates) and alum box upper intake. I need a system to run all this. I know of Fast, but want to hear how they are to setup and use. Looking for all opinions. Thanks in advance.

 

stock 5.0 ho A9L computer with a tweecer to tune it and the proper injectors and MAF meter...

 

yeah, I was wondering if that would work. It would save a ton of dough. Would I be able to get the most out of my setup and have it run correctly all the time?

 

With a supercharger and all, I would keep it simple with a throttle body injection like:

Um, and what lower are you using? I'm not aware of any EFI lowers for Clevor setups. A carb intake could be used and drilled for injectors and then you could use the FAST XFI setup. But XFI requires a ton of tuning.

 

Oh, just read my origional post, I'm running a GT40 lower (pricemotorsports adapter plates). Yeah I was wondering how much tuning it would take to get it right with XFI.

 

You can get it right easily with XFI, but you're starting with a blank slate. You'd need to load a basic tune to get it running, then give it a bunch of dyno time and alter the tables. But, XFI is used on a lot of wild hard to tune race cars because it works VERY well.

An alternative would be to just get a Clevor intake from CHI and run the Fast EZ-EFI. Bolt on, put some basic info in and let the algorithms do the tuning themselves. That would be cheaper all told that the XFI setup alone. The XFI ECM is almost the cost of the entire EZ-EFI kit with pump. Then you'd need harness, injectors....the XFI setups right now are going for around $4k iirc.

Though....I think they have an EZ-EFI computer that's designed to replace the stock 5.0 computer but hookup to the existing system....try that maybe? Basically run the stock type setup with larger injectors and the EZ-EFI 5.0 ECM. Let it tune itself.

Really, if you go with FAST there's about 90 different ways from Sunday you can set the thing up. Have you tried calling them?
