If you want any more oomph, chip it, makes a hell of a difference! :-)
Yes a remap would be an option, i can get it done through customers garages for £150, £200 if i want it done on a rolling road, plus the gent offered dpf removal, egr delete and if i feel really adventurous a bargain price on a hybrid turbo, fmic and a few other mods.
Doing anything past a remap will mean new brakes though and its my repmobile so i don't want to go crazy! A remap is on the cards though
