Performance upgrades on E500
I've been browsing on this site and seeing some people go with the Renntech ECU upgrade will others go with Powerchip. Is it worth the extra $$ to go with Renntech? Any other owners have experience with Kleemann upgrades?
I'm debating on who to go with as far as ECU upgrade, upgrade the air intake, and probably exhaust system as well. Can't do the headers, cost way too much.
I see that benz dealerships in CA have kleemann/renntech onsite and doing upgrades won't void the warranty on the benz.
Any help/comments will be helpful in me making a decision on what to purchase.
