shit, someone must have forgot to tell my beater. last time i went to hampton I got 28mpg on the highway with a stock reg and a 255. yea, there is overrun, but it's minimal and well within tuneability. It's only a couple PSI and only in vacuum. All the people that say it makes their car run way too rich would be surprised if they put a wideband on their car and did some tuning
