Its a buddies srt4 with a diablo tune on it. Misfires like crazy as soon as you get into it. Runs fine without the tune. Considering this tune is proven to work any other ideas on why its fucking up lol

it's the tune

i think im going out on a limb here, but i would say its the tune.

its the spoon

plug in tuners

That moment you are solving the problem while asking what the problem is.

Hes not gonna pay to have a basically stock caliber he doesn't even want anymore professionally tuned lol. There's no reason this thing shouldn't work. Something with the car is fucking it up.

Is the tune running more boost? It could be blowing spark out. Gap the plugs tighter. If it is running more timing it could be detonating. I can't watch the video right now.

probably just the car, srt4's are crap

tell your buddy to get a new car

The perks of knowing a few tuners personally I guess.

And if the car runs fine w/o the Diablo plugged in, chances are its the plugin tuner...
