After having a full scoobysport system, my car pops and bangs, almost as good as my race car.

I find that feathering the throttle on the over run at about 3000 revs, it pop's best, but will this do any damage?

*Sorry for being a bit of a Essex boy*

 

Pete, What year and model do you drive?
Keith.

 

It is a turbo 2000, uk car V-reg I think this is MY00, it has a ITG panel filter and a full scoobysport system, that's it
