- Increased Gas Mileage through fuel and timing advance revisions, DOD revisions and transmission retuning (Fueling has been reworked to eliminate lean and rich transitions, making fueling more consistent. Fueling has been leaned out @ full throttle)

- Increased Performance & Horsepower Timing advance adn fueling optimized for power and KR reduction under heavy throttle. Transmission "skip-shifts" enabled! (Expect to see anywhere between 5-20HP or more depending on modifications and mechanical condition)

- Reduced Likelihood of Transmission Issues Factory calibrations heavily revised, coding "cleanup". More progressive tables, higher fluid pressures, revised "torque management" reduces slippage, shudders.

- Lower engine temperature Fan settings recalibrated for factory thermostat

- Speed Limiters removed adn Rev Limiters raised

- Improved driveability through extensive transmission shift retuning and improved throttle response

- Will not affect emissions testing

- Runs on 87 octane in most vehicles with full performance benefits (If you have intake/exhaust modifications, you should be able to run 87 octane and achieve full performance benefits. If you have a stock vehicle, you may have better performance under heavy throttle with a mid-range 89 octane. Remember that octane refers to the gasoline's resistance to ignite, and has nothing to do with the "quality" of the gasoline)

- Timing Advance table in this PCM is highly modified over stock, it is designed to increase spark where available to increase throttle response and gas mileage significantly. At full throttle, your timing will be in the mid-gigh 20s, optimal for making great power on regular octane fuel. This is an increase of up to 5* over stock.

- DOD Factory settings are fairly tame and have been heavily revised. In 3rd and 4th gear, under cruise conditions at light throttle, you will find DOD activates sooner and remains engaged longer as you lightly accelerate. These activation and deactivation points have been carefully chosen not to bog down the engine when climbing hills. Timing advance in DOD have been heavily revised also, this not only increases engine efficiency while in DOD but also makes the engine much smoother. Maximum run-time has also been increased from 8 minutes to 10. There is no speed limit on DOD, it will activate at 150mph if conditions permit it!

- Thermostat We recommend to keep the stock thermostat. The car will run cooler, the low speed fans will engage at around 195* and the high speed fans just over 200*. An aftermarket cooler temperature thermostat cna be run, however the computer cannot be reprogrammed to allow the fans to come on at any cooler temperature. The reason being is the factory computer only controls the fans from 192*F and hotter. The low speed fans will also stay on for 120 seconds at key-off at temperatures at or above when the cooling fans normally run.

- Skipshifts Torque converter lockup will not engage until a higher road speed is reached, which greatly reduces city driving bogging. At full throttle up to 40mph, the transmission will downshift into 1st gear , on the highway, you'll find it even more noticeable as the transmission will downshift into 2nd gear anytime up to 90mph if given full throttle. GXP owners with TAP shift, you will love the changes that have been made! First off you'll notice the transmission responds quicker to your inputs, with crisp quick shifts. You'll also notice that the torque converter ("overdrive") will not engage, even at highway speeds while in TAP shift mode, which makes the vehicle much more responsive to your right foot inputs. When you're done playing, switch back to normal drive mode and the overdrive will re-engage.

- Air Conditioning is disabled over 3500rpm, to prevent wear on the compressor unit and regain horsepower that is lost in driving the unit. You may feel you're A/C isn't blowing cold if into the throttle for an extended period of time, this is normal and your A/C will re-engage once you lift off the throttle
