Message: [QUOTE="madpowerstroke, post: 322282, member: 5867"] Ok,here's an update to let the members know whats happening.Since Matt ran his truck,he's been trying to figure what happened.His truck would only build 26psi boost and on street hit 30-32 psi.Well it alittle hard to figure and Bill from PHP said his truck runs great on street but put it on Dyno and 22 psi.It's not the turbo and we have alot of things trying to figure this out.We think one reason could be the ECM not leting the turbo make full power on dyno but why?The other reason is might be Dyno,not loading up right,or possilbly both.Bill is loading truck up and taking to TS drag day tomorrow and see what track time will show.It least we will know if it's the dyno,if he gets boost up and gets good numbers.This all part of test and tune,the main thing is these turbos are just nasty,and put alot of air.One theory about ECM is that the turbos are putting so much air that the ECM is freaking out and cutting duty cycle on the VGT actuator.The other theory is the turbos are putting out so much air flow that,the ecm sees it as a non vgt since they are not suppose to put that much air.Well at least the turbos are go now it's the working together to get the tuning right,and the rest of the stuff.
