I actually think you are right about the mapping safeguard etc, because, as i say, when freerevving when not under load, the pops and bangs are just spot on. If i could reproduce this sound at will when underload, i think the exhaust aftermarket for the M5, would be redundant. Ive also noticed when freerevving, it will only pop and bang for a short span of time, say 6 or 7 bootfulls, then wont do it anymore, thus adding to the theory of a safeguard ?, all interesting and clever stuff. But the bottom line atm is, is the sound is being robbed by the damned OPFs. |

It’s either a new backbox, backbox mod or a removal of any of the other parts and a tune to remove the CEL. |

Has anyone done a resonator delete in the UK. Has it ever bought up a CEL on the car? I'm thinking of doing a resonator delete & potentially delete centre pipe between the two backboxes to give the car a bit more sound. Please let me know!

2 hugely different graphs. Lee, your torque rap up is very slow I guess it the dyno?? I have seen other evolve tunes where the torque is around 650-700lbs from 3k revs.
Weird as well why they never rev out (tune) to the red line. Turbo has enough puff. I guess its to be safe? its like having £100 in your wallet but you can only pend £80

What a shame, it's the only aftermarket exhaust I really liked the sound of.

I think the car needs a deeper rumble personally and more volume when driving hard. Quote:
