same...and i had the o2 issue but remember that it wont switch if constantly rich...luckily im not out an o2 sensor as well...

i agree...i got sent a tune with the 60s map for e85...im gonna try that and see wht happens...

Yeah OTTP is definitely a reputable vendor, but I honest thought that they had the tune down and there weren't all of these problems. Is there no one who has bought the kit, bolted it on, and been able to use their tune? BTW you guys are recommending a build motor now to run this kit?

i will continue buying OTTPs products, however i feel some store credit is in order after all that I have gone thru/spent money on this TVS tune
i agree with this ^. the kit was a great price and theyre a excellent vendor. the tune is the only thing that seems to be the problem. unfortunately i cant send you a file because im pretty sure were using the beta for all of our tuning.

on a side note a got the stage 2 mounts in and those are working great. lol

Josh,

I just ordered HPtuners from your website in hopes of being able to give OTTP viable information to resolve this issue for other users

I would hope that this investment on behalf of resolving this issue would warrant a discount on future purchases

I have to agree with this! Sounds like you guys are working your ass off and spending some serious out of pocket money to get this stage kit up and running, so people like me can order it next month
