Having my ECU programmed
Upsolute is well known in the Audi & Porchese community for good work & reasonable price (~$300-400). For Mercedes, they've done plenty of work on the 2.3 Kompression engine, on AMG one, on M113 (E430 V8), and plenty of diesel, but never a M112 engine (V6, E320), . I will be pilot customer for the V6 E320.
Promise is 20 Hp gain, and around 25 ft torque, with 91 octain gas (talked to Powerchip, but theirs require 93 gas, and double in price). And 10% saving on gas milegage.
Will update progress. Hope they will do good job on mine as they've done on Porchese & Audi world
I suspect that as Upsolute becomes more well-known here in the USA, they will do what Powerchip did by raising their price.
I've added the K&N performance air filter, and will be adding a Remus Sport Exhaust tomorrow...I suspect though, that any noticeable performance increase has come already with my Powerchip upgrade.
