I don't think mine had nearly 290bhp when Jabba finished with it either tho, but that really did make good pub talk!!
Thing is tho, ARE Stealth optimistic? I mean, if VAG engines are dyno'd in such harsh conditions, could it be that they produce that much more on the car??
Who knows??
Personally, I think JBS are a tad pessermistic (sp) from the figures I've seen, if a stock car only gets stock... maybe the accurate figure is somewhere inbetween??
What's probably best for a set of rollers is consistency, which most rollers (Stealth, Jabba, JBS, Awesome for instance) attended on this site's RR days gives. Do a mod and go back to the same roller and then you'll see whether it's made any difference
Now then, with all this discussion, have we actually answered Gizmo's question??
