Hey I'm running the stage 2 + AMS 91 octane map and I was wondering if I should contact an e-tuner or if this map should do, mods are ams intake (with heat shield), ams uicp, ams fmic, ams licp, ams widemouth dp, ams tp, and ams single exit exhaust. Wat do you guys think? Also 91 octane is the best I can get for fuel choice around me. Thanks.

 

It sould be fine. Just do log pulls and watch your knock count.

 

i did some logs and i also came up with a knock sum of 4 after a quick cruise down the interstate (about 3 miles exit to exit) i looked back at the logs and it seems to be that the knocks came after a stint at wot as soon as i let off. i wouldnt expect uicp/fmic/licp to be that big of a deal... i might get a hold of a e-tuner just to quiz them a little bit as im still pretty new to the evo. thanks tho, any help is much appreciated +1

 

you can also post you logs on the cobb forums and the guys there will tell you were to go from there.
