Cracks on upshift
Recently I have noticed a lack of the crack/backfire on upshifts at WOT. What I get now is a chirp (and no there is no bird in my engine bay) . I’ve tried multiple times redlining the car with my window down to listen for a backfire. From what I can remember this used to happen in stock tune.
Recently I had to remove my Eurocharged V5 tune as im was getting cams and lifters replaced by Mercedes all under warranty. I will be reloading the tune back very soon and then do a secondary cat delete.
I’m intending to do the gearbox reset procedure to see if it’s learnt my normal driving style for everyday use.
Do all you guys get a backfire on WOT upshifting.
