Just installed new tt chip and 60# injector combo in my TY. Had an old pit bull chip in it before, made 14# boost (has a manual boost controller) and ran well. With the new chip it beaks up over 10# boost. I tried adding more fuel, still breaks up and hesitates. I notice the boost reading on my Scanmaster reads almost half of what my manual gauge says. Manual gauge reads 10psi, my Scanmaster says 5psi. Not good. I installed a Racetronics 3 bar map when I installed the chip and injectors, and the chip is supposed to be for the 3 bar. Is the new MAP bad? Or a tune issue? I verified fuel pressure is rock solid under boost, I cranked up my adjustable regulator to 50 psi with vacuum line off, still hesitates over 10# boost. I have a 340 fuel pump. Thank you!
