renntech!!
Well, we got a notice from mb sugar land that they're offering to install renntech parts that are theirs. dad calls me into the room, and tells me to look, 625hp, and 740lbs of torque. he's going to be callnig them today i think, and MIGHT get it installed for the sl600 this weekend if we can get an appointment. since its a crazy jump in power...anything to look forward to besides a lot more of my insides flippin inside out?

My thoughts!
After doing the upgrade myself, I don't think you will notice that much of a difference with the car.
I also doubt that if you dyno your car you will get the numbers that they advertise in their upgrade.

Did you get a chance to dyno before and after? Most seem to think it makes quite a big difference but I know after spending the money no one would like to think it didn't do much of anything. I am wondering what Renntech does differently to the ECU than Speedtuning. Renntech is thousands and speedtuning is 550.00. If it is just plugging in numbers, couldn't they both do the same thing? I am contemplating doing this as well but am wondering why one place is better than another for essentially the same mod.
