I had the same issue after doing my intake and studs. It just seemed to be in the tune. Installed a new tune and it runs fine. But had identical symptoms on the looney setting. What did you one up with.
Yes there are several different looney sct tunes. The one that didn't work was a way hot tune before upgrade. I have another looney in truck now but not near as strong. She is working on a new tune forms as we speak.
Yeah I'm puzzled. I'm pretty mechanically inclined. I reloaded a few times way before this. Just got sent a new tune doesn't seem at hot of a tune but a little more than the street tune and working good.
I just did the absoulte ported intake and the wicked turbo wheel now my sct I the looney setting acts wired. It runs great on the tow setting and the street setting but on the looney it's builds 35lbs boost at less than half throttle but never puts you in the seat like it's not making any power...
