Best Upgrade for E350?
Need some ideas on the best power upgrade for my E350. Just got the car and love it and thinking of a PowerChip or the Renntech ECU upgrade. Other easy upgrades that won't void my warranty????
Will the ECU upgrade impact my gas mileage?
Thanks! I LOVE THIS CAR (my first MB)

Yup, ECU tuning will void warranty (if they find out...).
HP gains are comparatively modest (maybe 20 at the crank) for the money. Also, buying a chip long distance is not the best way to go about this - you should drive to the shop and have them customize the program that fits YOUR car best.
Unfortunately, the 350 engine is fairly new so I haven't seen much else being offered from MB tuning shops. Given the ever more stringent emission laws, just slapping a turbocharger on isn't quite as easy any more too.
