Has anyone tried or know of someone running a Holley Avenger 4bbl TBI? I'm looking to buy one to put on my 383 so I'm able to get enough flow to supercharge or turbo it. I saw they make 3 different setups for various aftermarket hp ranges. I didn't see many review out there on these systems. There quite pricey at $2000, Just want to get some advice or review before I jumped ship.

Thanks!

 

I know someone that has used the self tuning setup on thier MPFI system and they are happy with it. They self tune which will help with your 383. I'd say go for it. I do like the looks of teh FAST EZ 4bbl throttle body setup better tho. I'd say go for it. Pick the one for your power range.

 

My issue with the FAST ones is from my understanding you have to spend another 2K just to get the updated firmware in order to run a higher map. The standard is setup for only 1 which would not allow use of a turbo or charger. Again, this is what I gathered from reading the specs on FAST's website. I know little about TBI so I don't know how accurate I am. The FAST EZ-Tune is ALOT cheaper then the Holley if you go threw Ebay.

 

I did not know that. That is good info. If you do plan on going with boost then the holley setup seems to be a good choice. Traviz is pretty happy with his holley self tuning. But he did not use the 4bbl setup. he just used the ecm to run it and what not.

 

Check out dynamicefi.com(RBob). supports boost. as long as you are willing to spend some bucks consider port injection (dynamicefi supports that as well). Use a Pro Products single plane fuel rails and plumb along with a LS TB ?

Just seems spending the dough on TBI is well?

 

I want one bad, can I borrow your CC numbers???

It does cost $2k but I like that you can toss anything at it, and it will self learn.

not having to tune for NOS or turbo or both at the same time, is worth the money. tuning sucks unless your a pro at it.

 

This is very long but a decent read.Just got to kept in mind the source of the info through.
