550 Biturbo dyno before/after, Speedriven ECU only
 
Since this question came up on the E550 board, I thought it might be relevant to the SL550 crowd, as well. Enjoy!

Speedriven 550 Biturbo ECU tune. Otherwise stock.

Nice numbers, Is this a one day install?
Drop of car in morning and pick-up end of day?

Thanks,

George

Yes for the ECU, and doesn't require much notice (takes about 2 hours). For the exhaust, intercooler upgrades, etc. (basically, if you want to go further) the parts can be installed in a day, but we usually build the exhausts to order, so we'd take the order, schedule a day, and have the parts ready.

Just to be clear, with the exhaust I mentioned above, dyno'd out at 495-505 HP.
