Hey guys. I just got myself a 1999 SL600 in great shape. A couple issues to work out, but after I get it running perfect, are there any performance mods that I can do to this car to get some more power out of it? Exhausts? Intakes? ETC. This is also originally a California car.....are there any special emissions pieces on this car that are counter productive to performance?

 

We were doing big bore throttle bodies but stopped due to lack of demand. Honestly the best thing for the SL600 may be a custom exhaust system which will really help unlock a lot of power on that car. Also K&N filters may also help a tiny bit. Performance ECU software does also help and we offer that at a discounted price. Hope that helps.

 

you offer an ECU upgrade for the M120?

 

High-velocity, knife-edged throttle bodies.
PM me for details.
