If you are getting proper fuel cuts your car will be throwing some fault codes for fuel cuts and misfires.  The likely reason for it is that the Twintake is flowing a lot more air than your previous intake.  Due to the extra air air coming in while the car is boosting more fuel is required to maintain the specified AFR.  However the OEM pump could be struggling to provide that extra fuel.

At what point in the rev range are you getting the problems?  I would expect the fuel cuts to be happening from 2000-4000rpm as the cam which is driving the HPFP will not be spinning so fast making it even more difficult for the pump to supply the requested fuel. 

id say its around 3k-5k, im really thinking its the pump now. The car drives fast but when really pushing it it stutters. Think im going to put it to bed for a few weeks till my pump comes, then see if the problem is still there, il disconnect the battrey on my dinner and see if its still happens after that.

Unplugged the battery and all seems good now  :confused:

Maintains 12 psi as the lowest in 4th, also no splutters so may have just needed to learn it or something  :confused:

Also emptied my catch can

I've taken to only offering extreme advice to fix problems - just burn it out. It won't do it again.

Tug the battery for 15 mins and re-adapt the car, see if it still happens?

I am with Danza torch it.  :star:
