Re: Superchips for a 420SEL
I understand that superchips.co.uk makes a performance upgrade chip for the W(126) series. Has anyone used one of these chips in a W(126). What are the pro's and con's when using such devices. I'm also open to addtional suggestions on performance upgrades for this vehicle. Thanks!
