To echo comments on here and to answer the original poster, mine made 311 on a Revo st1, with an Autotech fuel pump added, but the real benefits are the car is totally transformed.
To be really honest I think most mortals on here could not really tell much difference when driving anything mapped to between 285 or 315 brake, so whatever map and whatever bhp figure you end up at you'll love the transformation. It goes good.
Would recommend it, my only down side was the insurance jump...but that's off the topic.
