Hello Guys today I installed in my evo 8 05 a set of GSC 272/272 I still have the stock ecu but here is the thing I started the car and when get to idle get to low in the rpm between 600-800 with the a/c 800-500 sometimes and the engine and the car shake like almost go to shut my question is Do I need to adjust the throttle bolt or What should I do with this? Is this Normal to happen with this cams? what is the lowest rpm at idle with an without the A/C on? thanks for the help

 

did you get the car tune after the cam install?

 

you need to get tuned! no way you can run such agressive cams and hope the ecu would adjust to it. After my cam install my car would stall with the AC on and on steep hills at low revs it would just stall. Get tuned ASAP and DO NOT GO INTO BOOST beforehand.

 

No i didn't tune it yet. So this is the problem needs a tune Is that right?

 

Your lucky u dont have cosworth m2s lol the whole car and everything on it vibrates... But you def need a retune!

 

Where'd you find 272 S2s?

Get tuned, what you're diagnosing is fairly normal post cam install untuned.

 

I bought it from a friend I found here!
