So i finally got Sherwin to remap the M3. Went to KAR before hand and did 228HP and 267nm at the wheels. Other stock M3's were doing about 221HP or thereabouts so it was inline. Today went to KAR to do an after run. Did 255 HP and 291 nm and it was still making power at 8500 rpm (previous redline was 8000rpm), i am very impressed. On the road the car is totally different. It pulls stronger everywhere in the rev range.
It still wasnt happy on the dyno though. The temperature inside the workshop was about 32 degrees. You can see on the graph that it was pulling timing due to the heat. But a dyno is a tuning tool, nothing more nothing less so the gain is what is important not the final figures. I had a 27HP and 32nm gain. That in my books is impressive going, especially on a car many tuners said that 5kw gain with software only was the max.
Sherwin, owe you bears
P.S Now before anyone here says that 228HP for a stock M3 is low at KAR, thats BS. When i first got my car I dyno'd 258HP there. So to come back and get 228HP 2 years later was a shock. But between the time i dyno'd the 1st time and now, the dyno has been recalibrated. Also 3 other Stock M3's also only dyno'd in the 22xHP range.
Mine is also one of the stronger stock ones (13.8 @ 162 at Tarlton)
