Driving the 951 today (about 3rd time out with it after repairs completion) and was accelerating. Boost came on about 3000 or so rpm and then as it got to a little over 4000, it seemed to go flat/come off boost. No noticable unusual noises. I have stock set up with reliboost, shimmed wastegate and CV disabled. Vacuum lines are silicone and were recently replaced.

Thanks

What does your boost-curve look like? What boost do you get at 4000rpm+? If you are getting more boost at 4000rpm+ than stock, you need the appropriate increase in fuel to match.

I will try to look at the gauge to see what level of boost I am getting. What is the limit for the stock FPR? I am running stock (cleaned and tested) injectors.

I paid attention to boost gage while accelerating when driving to/from work today. I noticed 2 things:
1. It did not have the same behavior (flat spot) as yesterday - it kept running strong to 6000 rpm today.
2. Instrument panel boost gage showed around 1.5 - 1.7 bar when under boost.
When accelerating today, I used a continuous increase pedal pressure. Not really sure how I applied the pedal yesterday (perhaps a much faster application).

My impression of the turbo acceleration is wow!
Thanks
