The need for speed.... 850 1995

I've been the owner of 2 240 wagons, and just recently purchased a 1995 850 Turbo Wagon. After driving the cumbersome 240's for about 10 years, it really feels nice to step into the nineties with something that has some pep. I'm quite impressed with the acceleration the Turbo engine provides. However, when I really floor the accelerator, I find the engine will hiccup. I couldn't say for sure, but I'd say somewhere around 5500 rpm's. Is this a preventive measure that Volvo has put in place? Is there some sort of sensor that does not allow for the car to accelerate any quicker? Thanks in advance.

    You are not hitting the rev limiter. The car would shift first. The only time I have hit the rev limiter is at 260 km/per hour. It does sound like the ECU my car does this ocasionaly after I reset the ECU.Howevewr it eventualy goes away. I would check your codes under A-2.

    I've experienced the same thing. Most often in 3rd gear around 5K RPM
    (I have a manual transmission in my T5). I think the ECU is adjusting
    boost to prevent pinging. I do not notice it all the time (seems to be
    related to air temperature, fuel I've purchased, etc.). My
    turbo is a 98 and the 98's ECU does allow a bit more boost and has more
    "controls" to back it off then earlier ECUs (newer ECUs are a bit more
    sophisticated) so maybe I'm just noticing it more with my 98. But I
    definitely can feel the power surge a bit at times.

    You could try resetting the ECU back to default settings. It then
    re-learns based on fuel, etc. When I do this my car is noticeably
    faster for a short period (then I guess it tunes back to the 91 octane
    we have for premium here in CA). To do this, disconnect the battery
    over night. When reconnected you will have to plug in the radio code,
    reset the clock and reset the radio pre-sets. Probably won't make any
    real difference but it is interesting to "feel" how fast my car is
    for a short time after doing this.
