Having the ppp fitted to my03 sti8 in the next few weeks but i prefer the blitz back box to the prodrive one so i`m leaving the blitz on.
Does anyone know whether this will effect the car in anyway ie. fuelling, spiking etc. or will it run fine because after all the prodrive box is straight through anyway isn`t it ??????????

 

can anyone help?????????

 

I don't think a back box could make such a difference except in noise of course and bear in mind the Prodrive is already straight through so IMO there is no problem with fuelling.
A mate with STI8 and PPP recently fitted GT Spec headers and so far he hasn't any problem at all so obviously PPP map is quite adaptive.

cheers Jim,
Anyone else got any views???????????
