I was really only curious if you picked up any power going from the stock tmic to the grimmspeed tmic, that being the only change. I wouldnt expect much if any, and I agree with the ease of installation. I dont plan on upgrading my turbo in the near future, but if i do decide to go that route I already have the cooling covered. I only went with the grimmspeed because i feel its the best one on the market right now. Sorry to thread jack with that question!
