Full Description

Use only with High Flow Downpipe or High Flow Catalytic Converter!

For the spirited drivers who want the maximum power out of their vehicle equipped with high flow downpipe or high flow catalytic converter. This software is intended to maximize your vehicle’s potential performance. The power curve has been delicately engineered to eliminate any dips in the overall powerband as well as maximizing delivery of that power throughout the entire RPM range.

*Transmission Tuning Recommended*
See Transmission Limiter information below


– Increased Boost Pressure
– NBT Display HP/TQ gauges calibration
– Torque limiters
– Lambda optimization
– Ignition timing optimization
– Optimized for xHP transmission tuning software

Additional options available with each OTS map
– Exhaust burble adjustable on-the-fly*, set the intensity without reflashing!
– Switchable maps on-the-fly*, select between maps without reflashing!
– Max Cooling on-the-fly*, enable the option without reflashing!
– Speed limiter removal
– Cold start delete (off-road use only)
– Catalytic converter delete (dcat, off-road use only)
– Exhaust flap control

*Adjustable burble and Max Cooling “on-the-fly” are currently supported only on F-Series vehicles. G-Series “on-the-fly” options are in development. G-Series require a 15 -20 second reflash (when using ENET) to switch maps. Switchable ethanol maps will be temporarily unavailable until next update which will allow you to switch between multiple maps On-The-Fly!


Vehicles equipped with an 8HP50 transmission will have a torque limiter. For the best results and proper smoothing of the torque curve without any transmission related torque intervention we have found that is best to increase the limiter within the transmission software. We present you with two options to implement this on your vehicle:

Option 1: Lifting the limiter in the transmission ECU which can be done for example with xHP Flashtool
Option 2: Bringing the car to our shop or another tuner for reprogramming of the transmission ECU limiters
