Sputter/power loss at 4.5-6000 rpms
Hey guys, I bought a 2014 Z51 with a Z06 package added, super charged, cammed etc. So she has 14,000 km on her and rides like a dream. This is until I go to race. When in neutral I can red line it revving easy with no problem, when racing, 2nd, 3rd and fourth up in the higher 4.5-6000 rpm range she sputters and spits, or cuts out. I took it back to the performance shop that had installed the a&a supercharger kit and they recommended I change out the fuel pressure sensor.... So after having dropped an additional 100$ on the sensor, the problem still exists..... 
anyone have any issues similar? I will try n post a video in the near future.

Drifting
Check the plug wires. I fried 2 wires and had similar problems. They are hard to get connected. I had to take the pass side valve cover off to get mine to snap in (w/ headers).

Melting Slicks
You might look at Traction Control and Active Handling.
They WILL interfere if they detect certain conditions.... and they will cut back on
throttle of and on (quickly), which might seem like stumbling.

Instructor
Who did the install/tune, and how long ago? I would try to take the car to a reputable shop and have them look into the ECM tune as a possible source of your problem.
Hopefully you arent getting any ping/detonation and causing some major problems.

Advantage Ford in Calgary sold me the vehicle knowing there was issues.... Also Davenport in Calgary tried to tune the faulty engine out instead of doing a full overview the machine. Costed me over all 110,000$.

Found out my engine was on the verge of blowing up. Engine was on the verge of catastrophic failure. Unfortunately I spent a ton of money on new plugs, tuning, fuel pressure sensors etc.... The fellow who bought it off me had the engine crater.

did they give you specifics? Sorry I’m not understanding?
why was it almost to a catastrophic point?
what was the technical reason it was having issues??
