So I bought Diablo in tune tuner for my 2012 300 srt8, installed 91 tune, I like the feel of the car, feels more responsive but it seems like power is the same or maybe even less now. So i read a lot and find out if you have intake and cat back system you need additional tuning for it to get most of it. And i do have airraid dry
technology filter/intake and Flowmaster force 2 cat back system. So I'm taking my car in for a custom dyno tune on Fri. I will post results to share with you guys. Can't wait to see what he can squeeze out of it.

I'll be interested in the results you get. Good luck, hope it goes well.

Tunes on the dyno can take advantage of real ambient conditions and your actual car being put through its paces.

I found the dyno tune to be most effective. It really accounts for the changes you've made to the car with an intake and exhaust.
