greentrbo95gst - I recently upgraded to the Turner Motorsports Race-Inspired M5/M6 exhaust. It is basically a muffler delete. Sounds really great. And as it so happens, it added something like 12 HP and 19 Ft-Lbs of torque.
Yes, I am looking to get it dyno'd at some point - although frankly, I can plug and unplug the RaceChip unit and prove to myself and everyone else that it works run after run. But, for the pragmatist in me (and just to have the dyno sheet) I would love to see the actual numbers.

please tell me more about the sprintboosters on our BMWs!!!!!!
very interested in the product for my x5 50i tuned with BMS....very familiar with sprint and what they do, but didnt realize they would already be available for our model year......keep me posted thank you!! |
The way it work just changing the pedal input to the ECU about micro seconds faster.
I don't think it eliminate the turbo lag.
The lag you get it caused by restricted exhaust gas flow.
More freeflowing exhaust pipe and catless dp would help. But dp will trigger CEL and no CEL delete solution yet for N63tu.
