2009 Dodge Challenger SRT8 Review

[jara97]

Finally took the plunge and installed the 91 canned performance tune and made a huge positive difference. I only have a aftermarket exhaust so I am hoping I am okay as far as setting with the 91 tune.

I have been using 93 Octane with the 91 Tune and runs perfect and performance increased as well as a major improvement in shift points. I still hope settings are okay as far as good for the engine but so far so good.

Thanks,
James

if you're running 91 tune on 93 gas, if you can, you should +2 timing and that will make more power.
