ok this is my question is a tuner like sct or diablo worth getting if you have a manual. my freind has one on his 06 charger r/t and its amazing like night and day and another friend wants to get one for his 99 svt cobra but its a manual. will this be good to get or do u think waist of time get some headers and some other stuff lemme know whats up so i can let him know

 

Definetly worth it. Go SCT xcal2 or livewire. Biggest results when tuning and having a cold air intake.

 

In stock form, a tuner may not be your best bet. But if your friend has several bolt'ons already, a tuner of some sort, will amplify their affects greatly. The only real difference between auto and manual tuning is shift point adjustment on auto's. On both however, you can adjust timing, fuel output, and adjust for things like exhaust or intake, and many other settings, depending on model of tuner/chip of course. Give this a read.

I have used the diablosport predator on my last 3 vehicles and I have no complaints at all.
