All orders will include an AutoTalent window decal

Description:

RennTech HHT (hand held tuner) allows you the unlimited ability to switch between tuned and stock ECU programming and requires no ECU removal. RennTech proprietary tuning module stores both the RennTech tuned file and your vehicles stock file. The module plugs directly into the OBD2 port and delivers the file you choose directly to the ECU. Programming takes only a few minutes and the vehicle can be reflashed at any time as many times as you wish.

RennTech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980s. RennTech experience, countless hours of in-house research, development and exhaustive testing ensure that our proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.

RennTech tuning software for Mercedes offers significant gains in horsepower and torque across the vehicle's entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine's rev limiter and modifying boost mapping for turbo-charged vehicles, RennTech performance software unleashes the true potential of your Mercedes.

With the RennTech ECU Plus Upgrade the W213 - E43 AMG Sedan gains up to +14 HP and +57 LB-FT, based on power numbers measured by RennTech. Please note that the Mercedes M276 engine performance when measured, obtains higher numbers than rated from factory. The maximum power number reached with the RennTech ECU Plus Upgrade for the W213 - E43 AMG Sedan is 416 HP and 471 LB-FT.
