Guys would anybody care to look at the attached? Truck was previously spot on before we made a few changes..Truck has an on3 Kit 78mm
1) Switched from Edelbrock Proflow back to a TBSS intake
2) Had the heads hand ported
3) installed 220/226 114 Lingenfelter Cam
4) Switched over to Deka 80's
I've used the David Steck File for the data on the 80's. Up'd my idle speed and bumped up the Base airflow and adjusted the timing in the idle sections. Truck idles fine. two things ive noticed is when im coming to a stop the truck immediatly wants to die and most of the time does.. Also when i start getting into boost the truck acts like its leaning out and starts to detect some knock. I havent laid into it yet and my new WB should be in this afternoon. Could low vacuum be causing the truck to stall out at low speeds? i loged the other day and it was around 40 and i could have read somewhere that it needed to be around 66 at idle.. Ive went through no leaks and everything is in mechanical order.. Just curious if anybody wanted to look and maybe point me in the right direction.. Thanks and have a good day.
