They were about 8-9 on the boost and normal vacuum. Boost should max at 12PSI.

Sorry guys I was away for a few weeks. The problem with mine was the tune. What happened was the meth was not working when I pulled out of the shop (wire popped off the Hobb switch) and it added tons of fuel. I fixed the meth after about an hours drive home but the tune was already shot.

The car is an animal now and made 486WHP on MaximumPsi's Dyno. Just for a comparison the renegade setup on the new HKS kit made 491WHP a few months earlier.

Not sure what a Dynojet would read.

I'll post the Dyno sheets when he emails them to me.

Sounds like you need to find a way to squeeze out another 12WHP to make it an even 500

Great numbers - I was kinda off the Renegade idea when you were having issues for so long. Seems like the way to go now...

With regards to the fuel meesing with your tune - did you just need to reset the adaptations? I can't imagine we would need a new tune everytime the meth doesn't work?

LOL I know that 12hp is killing me!!! This hot weather didn't help.... Another Dyno will fix that quick!!

If it happened again it would not need a new tune, they made revisions as well.

Spoke to soon!!! Took it for a few pulls on the highway and the issue came back. 4th gear it just stops at 6700rpm.... Zak at Active is lookig into it and will let me know if he finds anything with the tune. I will have my friend reset the adaptations to see if this temporarily fixes the problem.

They did multiple runs on the dyno with no issues at all. Zak made two revisions to get it right where he wanted it. It's crazy that after a few 100 miles it came back!!

Disappointed!!! But I guess it's part of the game!!

Wow that's really odd. Please post your fuel adaption values before resetting!

I'll try. I'm looking for someone close by to do this for me.

Do you know the name of the tool and how long it will take?

INPA or GT1 will do it no problem, 5 min tops.

Thanks, is there software available to download or is it only available with the unit?

Will this work? Found on ebay, says comes with software and will reset adaptations.

I mean it seems to be exactly what you need, similar to mine, but it's just a bit fishy that they say it works with windows 7. There is a guy in the FS here that sells the cables, I'd chat with him he seems knowledgeable.

I have yet to fix mine also. I am about to just go turbo LOL
