If you haven't already got one from Adrian, (D1 spec gt throttle controller) then do so, best plug and play mod ever. Really livens the throttle response up..... even after the uprev remap. Best £100ish pounds you'll spend. Whap it onto sport 10 and bingo
mmmm will have to look into these. ..tbh iv had the plenum spacer fitted and havnt noticed a damn thing either in performance or sound so hope a remap helps
