Dyno Graphs:

This last week I had some time to finally proceed with some long awaited mods to my car. I installed a KN Euro filter a few weeks ago so that is used in all of our testing. We then added a Akrapovic Evolution Exhaust and Powerchip Akra tune. Mike at Powerchip was excellent to work with and the tune made good power while addressing the Akra TQ dip and driveability. We used a reflash kit so the adaptations were not reset threw out the testing.

 

Car = 2009 E92 M3 Stock 18's

Dyno = Mustang MD1100 AWD

Run Notes:

  • Run#3 = 354 HP 258 TQ = Stock exhaust / Stock Tune / KN Euro Filter
  • Run#2 = 372 HP 276 TQ = Akrapovic Evolution Exhaust / Stock Tune / KN Euro Filter
  • Run#1 = 385 HP 284 TQ = Akrapovic Evolution Exhaust / Powerchip Akra Tune / KN Euro Filter


Test Conditions:

  • Ambient Temp = 30 ~ 35 Deg F
  • Starting Temps (Deg F)
    • IAT = 50
    • OIL = 199~201
    • H20 = 176

Dyno Notes

  • 3x 3500 CFM Fans on Front of vehicle
  • O2 Sniffer @ Tail Pipe
  • Tach signal delayed 200 rpm
  • DME Adaptation were NOT Reset for Powerchip Tune or Stock Tune
  • While the Akra TQ dip did not fully disappear with the Powerchip tune. The driveablity and feel improved tremendously over the stock tune.
  • 4x pulls were done per configuration. The 4th pull with the Oil temps @ 200 were always the best
  • 20-30 second stabilization procedure done for every run for consistent starting temps
