X5SND, your ride is one of the meanest E53's I have seen..! Nice..! As for the #'s, the guys at RMS are pushing my M54 to the limit. I feel I can easily blow my motor by over reving. The ESS kits are very conservative. My RMS kit was designed, machined, mapped, and tuned by the owner himself and is COMPLETELY custom. The shop owner trusted that my driving style was conservative and therefor gave my kit his all. I don't care about #'s, I care about reliability, and I certainly was not in favor of having them push my block to its breaking point numerous times just to prove something I already know. No thanks. Food for thought, RMS produced a 900HP E39 M5 dubbed the Monster. I will say this, imagine rolling in your X5 and you come up on a E46 M3 and he hears your pipes roaring. Knowing that your heavy weight X5 3.0 is no match he just gives you a silly grin and blows you off until... You down shift (boy I love my manual X5) to 2nd hit redline, into 3rd and run it all the way to redline as well, then hit 4th with no throttle. I got the jump and a good one, but the M3 did not pass me until I backed off. I am sure top end he would have passed me easily, but his facial expression when he caught up to me, PRICELESS. Some here on the board think that I am in a fairy tale, but I tell you, my fairy tale is a reality.


P.S. We still need to install the Methanol
