2014 F10 M5 Not Making Power
Trying to figure out what seems to be the issue with my car.
Put the car on the dyno before BM3 tune and it made 532WHP and 550 or torque car had downpipes at this point and no tune, after this my turbos went bad and i had Pure turbo rebuild them so my turbos are pure stage one. Did the BM3 stage two tune and the car made 572WHP at the same dyno and 659 of torque, after that i send the maps to Halim and he said my iAT where to high at the dyno, i am in south Florida so it is hot down here, So try it his beta stage two map and the car made 545whp and like 550 of torque, after this i replaced my intake filters, did the thermostat 90 degrees upgrade and change my coolant too to the BMW oem one. I had sent logs to Halim from BM3 after that and he says everything looks good that the car won't make any more power. Thinking of taking the car to local shop active autowerke so they can see what is the issue, any help would be appreciated. http://www.bootmod3.net/log?id=5c943eadae729b04494841c7 http://www.bootmod3.net/log?id=5c943...41c7:confused2 |

Took the car to active autowerke, compression on all cylinders is between 195 and 205, so they said is good, smoke test was good too, not sure where else to look anymore?

Thank you guys, i will change them this weekend, I got a misfire on cylinder 6 a few days ago, so replacing the plugs and the coils, all my injectors are new latest revision and were installed by bmw two month ago, Do you guys think maybe my pure turbos are not been efficient since i am not running methanol?

You can't really debug anything without logs. What is the boost level, timing, fuel trims etc.? |

Looking at your dyno graphs it looks like your rpms have shifted, is your tranny slipping?? The stock clutches slip above 600hp how many miles are you at?

Nothing yet, i am doing a leak down test on cylinder 6 since it is showing a high rough running value, but no misfires or drive train malfunction car is just not making any power.
All injectors replaced new and latest revision, Spark plugs NGK one step colder gaped at 0.18 and coils are new also, also both high pressure fuel pumps were replaced a week ago, Pure turbos stage 1 dont even have 5 thousand miles no smoke or burning oil. To be honest i am considering changing the car this is driving me crazy. |
