Hey i was wondering about the mopar perfomance ecu.
Is it necissary to run premium gas.
Also is it worth the money.
What are the hp gains?

thanks guys!!!!!!!

 

You don't have to run premium, but you really should. As for HP increase, that all depends on what else you have on the car. You should see about 10 hp on a stock motor.

 

If you don't run premium, you risk damaging the engine. The timing is much more advanced, and the PCM will not be able to retard timing enough on lower octane fuel if you start knocking (bad tank of gas). The PCM will be retarding near its limit just from you running regular unleaded fuel in there.

The PCM only takes a couple of minutes to swap out, you can do it in less time than it takes to fill up the car. That way you could keep the stocker in there for everyday driving, and the Mopar unit for a day at the track.

Best of luck!

 

sounds like now would be a bad time to get a performance pcm if you dont wanna switch it out once and a while...due to gas prices......2.99 for premium out here(today, but who knows about tomorrow)

 

LOL, its $2.99 for regular here.

 

just saw it for 3.19 regular this mornin

 

I used to fill up every day. Now I fill up every 6-8 weeks... Haven't checked gas prices lately
