i have a 2001 Silverado with a 72mm precision front mount, isky "triple 12" cam, deatsch works 60lb injectors, areomotive 340, 1218 springs, snow water meth, circle d 2c converter and a 4l80. I am running a 2bar os and the truck runs really good except when I try and turn the boost up to around 14psi or so it will go lean up top and I have noticed that the injector duty cycle will never go above 60% no matter what. I can try and add a lot of fuel up top and the idc will not go above 60, fuel pressure is a solid 70-72 psi wot. my tuner and I have looked through the tune many times and cant seem to figure out why the idc wont go past 60 so any help would be appreciated. I am also having a trans/converter issue that is also stumping me so I will post a trans log also for you to look at and express your opinion on what is happening there. it feels like the converter is trying to half ass lock after the 1-2 and 2-3 shift for a second or so and then it revs normally but this only happens at part throttle, wot it acts fine. converter was just cut and restalled by circle d 2 weeks ago and the trans is pretty fresh with a hd2. sorry for the long post but these two problems have been bothering me for a while and I have tried to fix them myself with no luck, thanks a lot
