Alright so i need some help with tuning my 4g64 turbo. Havent started tuning it just yet but plan to tune with a maft. I got a set of evo 560's and put em in to see how she ran untuned. I figured they were about 20% bigger than stock which is needed because the 2.4 needs 20% more fuel. So.... It actually ran better than the stock 450's at idle and cruising. It wasnt until wot that it ran super rich. Lowest the aem wb reads is 10:1. This is on 10lbs of boost just to be safe. So when i tune with the translator how would the 20% needed increase in fuel affect the tune in comparison to tuning a 2.0? Im not a newb with dsms but this tuning thing has me confused. I dont plan to run untuned and i cannot afford link. Help is greatly appreciated.
