i have the same problem with my 87/951, but mine it's a little different. If i kick down the throttle 1st redline(approx 80km\h), 2-redline(approx 140km\h), the car boosts all the way to red line, but in 3-rd gear at 5000-5500 rpm it's starting to lose power and if i keep te throttle down at around 200km\h the engine stops like it hits a wall, it's not just decelerating, that is with the sport driving.when I drive the car normal the problem it's different: 5-ft gear 100km\h ~2000rpm i push the throttle down it's accelerating but when i hit the 180 the engine stops again, that it's just for the first or second attempt because, after that, i have the same problem at slower speeds.I also have to mention that after the engine "hits the wall" if i press the clutch engine stops and can be restarted with no problem.
Another fact that I have to mention is that that if i ease down the throttle just a bit the car just fly and is going past 260km/h with no problem.
I think the problem it's with the boost because a few days ago I was in the second gear @3000rpm I pushed the brake an the throttle at the same tI'me, and when the boost indicator was around 1,9 bar - the engine has stooped again.
The car has this problem since I brought it and since I'm living in Romania i have no specialized service or even someone who could give me an advice.I think the problem it's the over boost protection but I'm not sure and i think the wastegate it's modified, also the fuel damper doesn't have the vacuum plugged I'm, i have put in one but with no result.
If you hve any ideea about how can i fix this, give an answer pls.
Thx.
