good point awaiting answer. Something to point out, by looking at the RR day results and chattin to my m8(Astra Sport Bloke) AmD are the boys. Just a chip and pannel filter and the guy is getting 194bhp outa his Vr. Same sorta response from the Astra sport guys. Think an AmD remap is the one to go for, but then again Vince use to work there, and if he can do the same remaps, then go to him. He's doing remaps on the cheap for VSR manifold buyers.
