Currently on the dyno with this one and this is the second time I have run into this with the exact same setup. On initial start the truck will idle rough and is very lean, about 12-14 secs after the fuel trims start ramping in and go to there max. At that point the idle stabilizes and about another 10-12 secs after that the fuel trims go back to normal and the truck runs great. I'm not having any other issues with either truck at all, both run and drive very well and make good power with the D-1. 540rwhp. I have attached a log of the start and one of tunes I am working on. Stock SRT8 Grand Cherokee with D1 Procharger and FIC 775cc injectors.
