Which Complete Flex Fuel Kit is Best?

Best Flex Fuel Complete Setup? Barth or Livernois

Can you please share your experience if you have either of these? From the research I found it appears Livernois came out with this setup first but Barth (and possibly other vendors) are a viable option for this setup.

I plan to use straight "summer blend" E85 most of the time but want to go with a flex fuel kit so Im not always hunting for a E85 station when Im traveling.

Thanks!

Injected Engineering or Livernois are the only shops doing actual flex tunes, that I know of. Mine was done by Curt@Injected. Barth's tune is an E85 standalone tune. An actual flex tune allows you to run 91 or 93 octane and E50-90 on the same tune, no pulley swaps, no tank draining. Injected also did a TCM tune as part of the tuning package. HPTuners allows you to adjust shift points. Not sure the Diablo platform allows for that. I'm at altitude, but I think I'll be able to hit 9s with bolt-ons using the Injected Engineering tune. Here's what it looks like on a Dyno:

Wow! Very Very impressive. Being that you are in Colorado how did they tune it? I assume mail order? I bet you have a hard time hooking up on the street!

The tune is done remotely. We data log on both the street and on the Dyno, email the info to Curt, and a few minutes later he sends back the files for upload. He'll set up a day and time for the tuning.

On the street the car drives like a pussycat. Don't really punch it unless I'm at the track. At which time it becomes beastly.

Good luck!
Wow! I wonder what your 60-130 times are? Probably low 5's with traction.
