The result - Just had my HPFP fitted by PSI tuning today (just off a500 outside stoke), very efficient, top quality service and great value, after fitting put the car straight on the rolling road and the result:
275 BHP at flywheel and 315lb ft of torque, v v happy.
Just what i was looking for, glad I stuck with superchips now. Not tracking the car, so don't need more (don't honestly think I would get that much more from say revo, and the car is a beast for the road which is where it is used)
Until sunday just running stage 2 was not a happy bunny, felt faster with each stage but a bit listless at low / mid revs, no check light but definitely lacking at mid rnage. Before I went for the HPFP fit and RR decided to change the diverter valve as a precaution - wow night and day, the old (original 2005 86k valve was ripped all over) with the new valve car transformed and on steroids, but did get fuel cut at ~ 105 mph on hard acceleration.
But with the HPFP smooth as butter all the way to the red line.
Car is 55 plate GTI K03 turbo, 86k on the clock, milltek turbo back with res box, autotech HPFP, ITG CAI and superchips stage 2+.
Moral of the story, fit a new diverter valve and get a good quality CAI (i went ITG) and an HPFP and superchips is a good for the power.
Big thanks to PSI (am def going back for my next cam belt change and any other work that needs doing, v professional outfit) and Superchips for excellent customer service - especially michael alvey anderson.
PSI said the biggest isse was the car kept trying to climb out of the rollers with all the torque, and it drives v v nicely and I got 35mg av driving back to cheltenham at 85 - 90 mph (70 officer honest)
