I just did an ECU flash with Oliver at www.speedtuningusa.com and am very pleased with the results. I was only looking to remove the speed limiter. I got that and some extra HP and torque to boot. The car drives better and is quicker..........all for $350. Well worth it!

If you really want the whole 'meal deal' of upgrades, go to one tuner who can provide them all and importantly tune your car to run correctly with all the mods together. I would not try to mix and match engine parts and tuning, it is certainly a recipe for trouble, something you don't need with modding any car let alone a SL55.

Personally, my pulley, chip and filter combo was organised by a tuner here in Oz and installed by my mechanic/tuner who is affilliated with the supplying tuner. It all installed flawlessly, took very little time, car performs brilliantly as a result, and there are no obvious signs of modification. I am currently awaiting pricing on a Supersprint exhaust package (couldn't justify the lovely Eisenmann stuff) and also for headers which are due to be released shortly (still in final development stage).
