I installed an AEM wideband and when I start the truck stoich is 14.6 and within seconds it drops to 10.0 at idle. Normal driving is 13.2 with alot of fluctuating back to 10.0 wich is killing my gas mileage if this is true. I'm waiting on an authorization code for VISTA from Scott at Detroit Turbo but until then I only have OBDII scanners and software which does me no good. The truck has 42# injectors and an ultimate chip. I've tried every setting and no luck but I need data master to see whats really going on with the fuel trims. The truck runs great with a new exhaust system, no cat, gt35r compressor and TD06H turbine at 17 lbs of boost. I have all the tuning software needed and more form Scott and was wondering what some of the ODBI experts have to say. Hopefully I can log as soon as I get my code.
