i have to say i had a tt t38 on mine and was awsome.. i thought next step gt3076 and to be honest wish i had kept the t38.. for the extra little performance even though its been mapped properly this time where as before just a chip my money would have been better spent elsewhere on mods.. but guess if i was going from t34 id go gt30 too..
although ill see if a std exhaust cam and remap on autronics makes it a bit nicer soon..
