I have a 2007 335i I've done a stage 1 remap, alpina b3 gearbox flash, full service, gearbox oil changed and intake valves walnut blasted. But the car still feels sluggish when driving in D mode. When I switch to sports mode the car sound very loud through the exhaust but still feels sluggish. I had a E46 m3 prior to this very standard and that felt quicker. I was under the pressing when a remap is done to these cars they are quicker than the E46 m3. Can anyone help pls need some serious advise?

What petrol are you using?

I find a big difference in performance in my car running on Shell V Power compared to any other fuel I've tried.

In some cars like my 3.0 z4 fuel doesnt seem to make any difference but in the 335i it really does.
