Power Loss, poor starting

Model: 996TT, Year:2003, Mileage:28,500, Type of use:Street use only
I have K&N filter, billet blow offs, B&B exhaust and Unichip installed on 2003 996TT. The car has amazing power - until last week. From idle to approx 3,000 RPM everything seems normal but from then on, the engine chokes on itself - no power.I looked for vacuum leaks but found none. The car had difficulty starting and the CEL came on. I cut power to ECU, re-established by turning ignition on for 60 seconds and now the car doesn't start at all.Any ideas?

Can you tell me if the car had as standard equipment a pop-off valve and:1. If it did when does it need to be replaced - what are symptons?2. If it didn't come with one what do you recommend I do to install one - I hear from Ellis porsche that Porsche doesn't make a good one and that an aftermarket is best.Please tell me as much as you can about this valve. Thank you.

2007 997tt Idle creep when warm

Vehicle Information: Year: 2007; Engine (Size, Modifications): 997TT; Total Mileage: 20100;

Twice now over the past 3-4 months, when I've stopped at a light, the idle will creep from 850 rpm or so to 1200-1800 over 5 seconds or so. It will pop back down to 850 for a second (sometimes by itself, sometimes after I blip the throttle a little), then creep up again. The first time it happened I parked the car and when I went out the next day it was fine. Today it happened again. The car was warm both times. Weird - any ideas?Thanks.

Is there any truth that the new generation Turbo engine (2010) will be based on the Carrera 3.8L and not on the race 3.6L?
