Jerry: About a year or so ago, I took my stroked Uber up to FM to have them take the Uber off & change over to the FMII turbo. I chose to go with the GT3071R, well let me rephrase that, the stroker motor demanded that I go with the 3071 (it is a harsh mistress!). It's very drivable on the street. I'm not sure how close to 300rwhp I'm at, but the greatest limiting factor that I have is that I'm not very good with the Hydra tuning. It sure does put a smile on my face & surprised looks on the drivers of other cars when all they see of my car is tail lights.
