Does anyone know what would be a good performance chip for my 2003 SL500? I am looking for a few more horses and some torque to get off the line?

 

What year is your SL and what's the minimun hp gain your looking for ?

be careful , ive seen cars get really screwed up from people trying to do that. all sorts of issues and they end up costing alot of money to fix......try porting and polishing of the heads and better exhaust first. or stick with a company that specializes in Benz performance. do some more investigation before just making a purchase.
