Golf mk4 GTI 1.8t remap to 215BHP? - perleman
Guys,

Have seen a tempting remap from Revo for £500 to take me to 215BHP from 150 - seems a little far fetched but the guy told me my car has the same basic engine used in the TT 225BHP so lots of potential. I have read posts on this site about chipping but was hoping for some further opinions or thoughts - VW will do it officially for £611 to take me to 180BHP but that seems like poor value for money. Revo is attractive as it is undetectable (I still have VW warrenty).

Yes 215bhp is quite achievable, however only by changing the fueling, timing and boost which all put a tremendous amount of stress on the internal working parts,head gasket (if not changed) and of course the turbo itself. Be prepared for repairs and half the working milage.
Of course all this is additional to uprating the brakes, suspension etc.

Do you think the official VW Superchips map (takes it from 150 to 180 BHP) is a safer bet for longevity? And what sort of performance gains would that 30 BHP bring - is it worth £600?

Try www.upsolute.com for a re-map same as superchips but only £300

Nothing is undetectable mate.

In this case, it is rather easy to detect. You put your foot to the floor from a standing start and it is quite apparent that you have 200+ bhp rather than the stock 150 bhp.
