Headers, cai tune.
Bought my 2015 Zl1 two weeks ago with mods already done to it. Dealership had no idea if it was tuned so I scheduled an appointment with Speed Inc to make sure it was safe. Well today was the day.
2015 M6 ZL1 8k miles Kooks headers with high flow cats Borla Atak cat back Cold air inductions intake. The car was lean in the lower Rpms and very rich up top. See graph below So I had Speed Inc tune the car. Results where 567whp and 540wtq Car drives awesome. Power is awesome. My last car was a 1998 firebird formula with cam with almost 200 less whp and 170 less wtq. Needless to say I am very happy with the car. |

Top graph is before the tune. Bottom is after the tune. Ended up making a little less tq after tune but much safer made the same hp but carried it better.

Probably didn't see another 10hp after tune because of heat soak. If you did another cold run I bet you'd see some improvement. No reason to do it just saying.

Yeah exactly. I just wanted the tune fixed and the numbers where a bonus. I will get a pulley in a few months and get another pull on the same dyno. Will be nice to see the numbers then

Might have not seen a peak gain, but from 5750rpm to roughly 6250rpm there is a nice gain from before and after the revised tune.

Yes there is. I was super happy with it. I thought I would lose power with how lean it was at first.
