Yea that is alot and sorry to hear


Fyi a good safe general rule is 1 psi equals 1 * pulled from NA

Stating how most older motors will take 28*-29* NA
And how newer will take 26-27

Yeah I've gotten past it now. Just goes with the business of going fast I guess. And thanks for the info. I always enjoy reading your posts...so much info to be had. I had lots of $$ then, now I don't but still going to do something fun in the near future I hope. God is good and life is too again.

I'm sure you are smarter than that "tuner" was. Your error was running on 93. Bottom line is, setting up and executing a safe and good boost tune is easy and anyone who says otherwise is full of

Thanks! What are y'alls thoughts on thetuningschool.com to learn how to do it myself or should I just hire a local expert as I have planned? I've got hp already but this '14 and up stuff is expensive if it's screwed up!

Practice on it while it's N/A......the chance of you blowing it up should be nil. Then read, read, read before you push it.

Or, if you don't want to put the time into it, I'd find the best tuner out there.
