Final got this thing on the dyno and made 486 rwhp and 446 rwtq. It was tuned on a super flow dyno at Karl's Performance.
Just got it back today and I love this thing.
Also, I would like to mention that I bought this kit used from jclayc, and overall it was a very positive experience. He was great to deal with and I am appreciative of that.
If it were me, i would get the 90mm upgrade, add methanol injection and relocate the batt to the trunk for more weight balance.
Stay simple with the meth injection, snow performance makes great plug and play kits. Just dial it in where it turns on when your injectors are 5% higher than cruisin and have the power jet open when you hit 2-3psi of pressure. Dont alter anything on the tune but notice your iat drop and the power curve just keep goin up...
If its a daily driver get the camaro rear fender tank and work it all together. Then you will have a perfect dd with so much more potential.

How can adding meth(Fuel) not effect the mix ratio in essence making it super rich? I have read this repeatedly and I just don't get it. I understand the cooling effect that meth provides, but it is also a very effective fuel. How is proper mixture achieved without altering the tune??
I tuned my truck with no meth and went for an AFR of 12.8, i activated the meth and it dropped to 12.2.
You are right, the AFR does change with injection, but its not a huge deal, we are talkin about 0.6 afr, which is in my case, So if you have a 12.0afr you will be fine for it will drop to 11-11.5afr, however, if the AFR drops too far down, then you are able to reduce the methanol injection and get the AFR you want, this way you get a comfy AFR without the injection and ultra safe afr with the injection.
I could reduce the nozzle size and it will raise my AFR, but i lose on the coolin power, i have my IAT tuned out where i go from 126F down to 75F. I didnot alter anything on my tune, but i did relocate the IAT sensor from the MAF to just before the TB. This way i take advantage of the cooler charged air and my ECU will adjust the timin and fuel curve so i see more power on hot days.
My next idea is to add another stage like my caddy where i have my normal nozzle turn on at 85F then a second nozzle turn on at 110F, this way i have a more balanced system and i am not wasting so much injection on days that are cooler than 110F.
