Sudden loss of power
Hey guys i need to pick the experts brains. Let me give you a back story on my car. Its a '17 2ss M6, mods are
Pray ported T.B. / I.M.
Roto Fab intake
EFI e85 sensor
ARH 1-7/8" LT w/cats long system
Mighty Mouse catch can
MSD wires
New Stock Plugs
HP tuners tune
Made 433 on mustang dyno w/e50 or so.... mix of 93 & e85
458 on dyno pack w/ full 93
When i installed the headers i broke a spark plug wire, that gave me a misfire. So i changed all plugs n wires. Now the Pray ported TB....... bro this thing was major headaches from the get go. Car would always go into reduced power mode all the time. Sent it back, he gave a another one but with out the shaved down blade bar. Its been running good since.
Now my new problem is i had her out yesterday, doing a few WOT pulls here and there.... that was all good. But as soon as i had to drive thru the streets and lil traffic for about 45min or so. She started to act funny. From a 2nd gear roll i smash the gas, there is the initial torque pushing back then a split second later it feels like she pulls timming. It had no power any more. No check engine light, no traction control light, nothing. I did this a few times and all the same result. So i just drove her nice n easy back home.
So my question is what do you guys think this could be?
