aup guys,

when i`ve been driving for a bit then let my foot off, let it dye to about 2000 revs then just prod the accelerator then the car lets out an almighty backfire (sounds kewl). is this just the excess fuel being burnt in the downpipe (not running a cat or centre box?).

i notice burbling now when letting off the revs but i`m just wondering if this bang could be something more serious?

(my mods are as below)

so even with the exhaust straight through and being chipped, shouldn`t i be expecting a little of this? the maf is only about 13k old (if that!!)

Ollie my mates car used to back fire when he took his foot off accelerator to change gear plus he was getting very low mpg.

my jetex system on the cupra 20vt did it all the time. Nowt to worry about. Thinks its a mixture of air/gasses in the exhaust system. Sounds cool.
