Lean running if you increase the boost.

Very twitchy boost when on the motorway etc, a touch of accelerator will give it full boost.

Boost will be either on or off, not tapered and mapped as when the ecu controls it.
Full boost / part throttle = lean running, which leads to hot running, and can (although I'm convinced this is an old wives tale although is technically possible I suppose) lead to cat failure. if the cat in the up-pipe fails due to heat breakdown it could fire bits of cat through the veins of your turbo, which isn't too desirable...

Overall;

Whilst you can get a bit more boost than with the ppp it could be very costly, and IMHO the costs and risk outweigh the gains. You will also knacker the driveability of the car.

I wouldn't even consider it unless you have a boost gauge, knock-link and ideally an EGT gauge too

Sorry if this isn't what you wanted to hear matey

I wouldnt. Its a bit crude for such a nice new motor.
£30 is money best spent on servicing or maintainence.
Save up perhaps for a nice set of wheels other mod which should give you a buzz too. (i pressume you are getting bored?

yeh good point. I wouldnt fit one without a knocklink - another £150
Then theres the guage and pod. AFR ideally.

 

Ive got one fitted, but I waited till I had an Apexi PFC fitted at the same time.(Ta Andy F)
I wouldnt use one on its own... too much too risk I think.

 

Thats cool, thanks simon, thats what i was after,a direct no nonense opinion thats answered all the Q,s i was after.

I wont be fitting one

 

Yep i am ! , i will set my sights 4 Eibach springs instead
