I have seen reviews on IPD ecu upgrade from, not impressed to WOW!! I really just need to know if the difference is really worth the money.If the difference is not outstanding then maybe I will just leave well enough alone. The car is already pretty fast. <BR>(wouldn't keep up with my STS though!)<BR>Thanks very much for any responses in advance.<BR>Ed<BR>95 850 Turbo

I purchased the ipd ecu for my 855 turbo a few years ago and after a week I sent it back. It does something, but not nearly enough to justify the money I spent. Most of the power you gain is in the upper RPM range and I just don't drive above 75 mph all that often. As for off the line, I really couldn't tell the difference. I guess if I had a stop watch there may have been a difference in times. You would think that a 53 hp differece would have a big effect on performance that you could just feel. When I upgraded from a Turbo to an T5-R I felt a bigger difference in off the line speed and that is only a difference of 18hp. You could always try it and if you are as dissatified with the ECU as I was, you could always mail it back. Good luck.<P>

I decided not to upgrade the ECU and did an MBC and notice definate power gains. Best part about it is the turbo spools more readily than stock, not that my 855T suffered from serious lag.<P>If you should go this route search google for MBC. I paid $35 for the Dawes unit and install took 20 minutes (max). What the boost as the T5 turbo motor responds wellm, but is sensitive to overboost.<P>David M

I picked up a 'previously loved' ecu on the cheap this spring and I'm actually very impressed. I need a good exhaust, but nobody locally mandrel bends pipe (dammit!) and I'm too cheap to pay $700 for ipd's exhaust.<P>I think the difference is night and day b/w the stock and modified ECUs. One thing to note is you must run 92octane or higher. I put some 90 in once and the car hesitated something aweful under full boost. Now I feed it 93octane and the car's very happy.<P>Imho, throttle response is much better than stock, and rolling start power is way up from stock. I feel the price I paid was justified, but the 'new' price is too much for what I'd want to pay.<P><P>

I have a manual boost controller on both of my family's 850 turbos, and you can feel a huge difference in performance. For the price they have got to be the best performance. If you want, i can sell you one for $25, and If you dont want to buy a gauge, I could set it at a certain PSI on my 850 turbo so that you could be safe.<P>Pete

Thanks for the offer Pete! I will let you know if I decide to go that route.<BR>Ed

Personally, I would go with the BSR... Its only $650. It is a hair more agressive, and you also get a cone filter to boot. (you will aso hear the woooosh of the recirc valve...)<P>
