2011 SRT Challenger GWE
What would be the best tuner to purchase for a 2011 SRT Challenger?
That's because srt8s are set up for 91 stock. With 93 you may notice a little more but even then you're only talking 5-10hp without any other mods.All i can say is i just put a diablo tuner set to 91 octane and disabled traction control on my 2011 srt8 and if theres any difference its slight. Might help an auto more then my stick with better shift points and firmer shifts but to be truthful i felt more of a difference when i put the peddle commander on it and even they it wasnt near the differnce that made of my 2020 ram auto. If you live near somewhere that dyno tunes (i dont) then id say save your money and have a proper dyno tune done. Maybe part of my lack of feel is i already had the peddle comander and you can ajust that too with the diablo. but if you want a handheld id go diablo. Ive had a half a dozen of them and they all worked flawlussly.
