Hi all. Picked up a 2015 ZL1 M6 with 12k miles, a few months ago. Dealer didn't know much about it, i.e. said it had no tune; but noticed it had an ATI 10% lower and a Rotofab CAI. Thanks to the info on here, figured out it must have a tune. Took it to JDP Motorsports and they kindly read to see if it had a tune.
Found out it is tuned but stock injectors.[emoji15]
Queue the upgrades. Figure if I was tearing into it for injectors, what else should I do at the same time while I was already in there.
ID 1050x injectors
Ported throttle body
Ron Davis HX
D3 HX tank
Tr7ix spark plugs
Taylor wires
2.5 supercharger pulley
100mm idler pulley
American Racing Headers
Ngauge
Alkyl Methanol kit (safety measure)
Sorry for the long intro, love the car. Even more now that I got it back from JDP (can't say enough good things about them) last week. It made 650 RWHP/650RWTQ
