yeh, i am only on a street tune atm, be lucky to have 110rwkw, but its my turbo that lets me down in the lag dept. Its a high flowed, Journal bearing item with a larger VG30 housing. Its strong, but its slow. Ill see how it goes when i get it tuned properly again and then go from there. I would love a GT30RS or similar, but I didnt win lotto..
