Hi Guys

Hopefully you could leave this up just for the day as this could also be helpful to RS4 Turbo's with similar problems.

I have a 996TT Tip, my boost reading has always been 0.5 and never above, I never thought anything about it as I have never had the ECU flashed and most Turbo's read between 0.5 & 0.7 anyway.
I have just had the ECU flashed (PSI flash) and it is still not exceeding 0.5, PSI say it should hit between 1.0 & 1.2 (also have a fabspeed system installed) There is an increase in power but that's me just feeling the boost coming on early, which the PSI flash does, but it will not exceed 0.5!

I have replaced DV's and still getting 0.5 although it hit 0.6 once! I have now checked all intercooler connections, given the F-pipe a good inspection, The DV's have been replaced!

What do I look for next?

Someone has mentioned "WASTEGATE"

Could anyone here help me out or advise me of a specialist!

Umm....this really shouldn't be here...why not try the Porsche Forums ?

- having said that, surely PSI (whoever they are) are responsible for ensuring your car is ready/healthy before they re-flash it and potentially make things worse.

check your boost levels with a seperate analogue boost gauge, not the factory digital readout. On some of the earlier turbos I had cars running 1.0 bar while the readout in the car only read to 0.6 or 0.7( cant remember exactly).

Hi Dave

Yip! I know i'm pushin my luck a little with this one, but I still love you guys!!!

The reason I have posted it is that a lot of ppl might have similar problems and don't know it! And the Porsche set up of the turbos is similar to Audi!

I got it flashed in the States from PSI, got it for £1500 all in!!! They have been very helpful but have mentioned there is a boost leak!

Thanks
