SL55 AMG
Speedtuning ECU For SL55...
I just had my '04 Porsche Cayenne Turbo ECU flashed by Oliver at Speedtuning and I'm very impressed with the results. They claimed a 70 HP and 90 FT.LB. increase and I believe they're damn close cause this baby flies now! Boost pressure was raised from 8.5 psi to 16 psi, timing was raised, fuel was added and the speed limiter was removed. $600 well spent but my question is has anyone had their SL55 sone by this company? Oliver says that the ECU for the 55 costs $300 and yields 32HP and 32 FT.LB. TQ but the pulley (25 HP) is still overpriced at over $2000 and he recommends having both installed at the same time on the 55... Anyone with experience with this Maryland based company?

My SL55 was done by Oliver and it was $$ well spent. I wasn't after the extra power as I think the car is fsat enough. I wanted it derestricted. The car is definitely faster and on a deserted unamed western state, on an unamed road the SL WILL wind out the speedo and then some...........probably 202 or so. Pretty impressive with the seat heater and massager going!
