A remap on this engine doesn't bring that much, maybe 20-25 hp at the most, not something you can feel on this car. Doubt also that there will be a measurable mileage difference...

Spoke to Overfinch, JE Engineering & Superchips who all offer no more than 15 hp increase and all suggest its a waste of money on the S/C.

Smaller pulley and a remap is supposed to give around 40 to 50bhp? Cayenne Turbo "S" 521bhp Standard

Ive had both remap and pulley done with the supercharger & inlet manifold ported ... it has made a big difference. It does push the power further up the rev range so you do tend use sport mode often to keep the revs up.. but it leaves a standard s/c for dead 2006 RRS Supercharged

which pulley. 1.5 or 2.5psi increase? I am going to go with 2.5 psi increase and fit a larger flow intercooler pump and maybe look at flowing the inlet manifold and supercharger. Inlet temps seem really high. need to get these down to make good power. Cayenne Turbo "S" 521bhp Standard

The plus and minus leads where switched. I noticed this as the new large pump I wanted to install didn't run properly, there is also a TSB for this with the vin range of affected cars, but can't remember the number.

Did you get the mapping & pulley done in Dubai? Do you mind telling how much it cost and what spec is the pulley? Mark Adams will be in Dubai early in January, I've had mapping done by him before...he's the best in the business but also quite expensive. Thx. |
