Talking Evolve dyno tuning day! e46 M3, e39 M5, e60 M5

Got three cars dyno tuned by Evolve on tuesday. I'm super excited with the results, the cars feel amazing. Mid range on the e46 is beginning to feel like it did stock on the e39 :screwy:

Equally impressive as the gains, to me, as how identical each pull was to the others of the same tune (pulls were done in groups of three). They lines were pretty much identically overlaid on top of each other every time. Super consistent! Everything also still feels like stock, or better. Completely smooth, flawless idle, perfect throttle response. :parrot:

The entire process was a joy, and actually a really fun day. Strap down to the dyno, do three pulls, send the data off to Sal, he'd review it, make some tweaks, and minutes later we'd have a revised file back to flash on the car. Rinse, cycle, repeat until the car was optimized. The e46 and e39 took 3-4 tunes to get it spot on perfect, the e60 took a couple more because we didn't realize going in that it had a bad MAF so it was returning bad data. Once that was sorted, 2 more tunes and it was perfect.

Gains shown are from the dyno tuning alone. No hardware changes were made and each car started out with an evolve tune (so total tune gains are greater than what's shown in the graphs).

Every car has over 100,000 miles on it. Some significantly over.
