Just had my HPFP fitted by PSI tuning today (just off a500 outside stoke), very efficient, top quality service and great value, no affiliation blah blah blah, after fitting thought it would be rude not to get the car rr'd and the result:
275 BHP at flywheel and 315lb ft of torque, v v happy.
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+.
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)
