Well as the topic says, what would be the best step to take in order to gain more performance. i would like to hit around 290-300 rwkw. Would it be best to just change the stock turbo to an aftermarket one or what do you recon. And what else should I also replace in order to make it a safe tune. The only things done to the car so far is: Full 3" exhaust Apex'I Dual Funnel intake GReddy Type-RS bov Greddy front mount intercooler Tein suspension R32 ecu+chip Thanks for all the help in advance
