DTE Stage II PCM Performance Upgrade

We have developed a chassis dyno derived Stage II performance PCM calibration upgrade where the calibration was written using engine operating data obtained from the chassis dyno and from extensively driving the car in real-world conditions that the average customer may encounter from day to day. This calibration is compatible for either 91 or 93 octane pump fuel and the testing/engineering was just finalized recently.

Currently it's available for the 2004-'05 model year vehicles with M/T and either Fed. or CA. emission regulations. This PCM calibration upgrade is made available to you via mail-order, or you may come by the shop to have the upgrade done for you here at DTE. This second PCM upgrade package is specifically written for a vehicle that is equipped with a Corsa exhaust system and a cold air open-element airbox. (such as LPE or More) Other exhausts and/or CAIK used in street-trim may be also used with this calibration.

As always, the drivability and power provided by this upgrade can be felt all over the powerband, cruising and at idle speeds. Fuel mileage will increase approx. 2 MPG over stock as well. Expect power increases of 3 RWHP/8 RWTQ respectively over our Stage I performance PCM upgrade and 16 RWHP/16 RWTQ over stock with the addition of these HP components used in the combinations listed. We immediately noticed the increased torque output this combination produced over the Stage I upgrades making the car A LOT funner to drive over it's entire RPM band due to the increased power under the curve, as compared to stock.

Below are some figures we've documented from those tests and all subsequent dyno pulls were finalized on the same day, by myself personally, with the engine temps within 3* either way of the run preceding it. All control conditions varied by about 1% +/- throughout the testing session. Three pulls were made for each respective change for accuracy and the highest of the three was recorded.

This calibration was written operating the vehicle in actual normal operating conditions that would commonly be found in every day, go to work/in-town type driving.

Dyno Cell and Vehicle Control Conditions:
Ambient temp- 47.3*
Absolute Barometric Pressure- 29.16 in./Hg
Vapor pressure- .19 in./Hg.
Rear Tire Rollout Ratio- 48.98 RPM/MPH
SAE Correction Factor- .98
Rear Tire Pressure- 33 psi
Engine/drivetrain temp.- 190*
Vehicle Mileage- 8114.0

100% Stock:
340.6 RWHP/338.6 RWTQ

DTE Stage II Performance PCM Upgrade w/ Corsa exhaust and open element cold air kit:
356.7RWHP/354.9 RWTQ

Refinements Include:
- CAGS deleted electronically. (removes function AND turns off annoying dash light all at once)
- Quicker wide open throttle activation
- Reduced engine operating temperature range from O.E. Now 195*-205* (O.E. 215*-233*)
- No A/C drag when WOT is selected and A/C is on. (You now don't have to turn off the A/C to get maximum power at WOT)
- Idle quality smoother
- ZERO detonation
- Accurate fuel and spark curves
- Annoying "popping" sound from exhaust eliminated on decel and during shifts
- Compatible with 91 or 93 octane fuels
- Removal of speed limiter
- Emission compliant
- +2 MPG increase with highway cruising
- 16 RWHP/16 RWTQ gain over stock

Chassis Dyno Graph

This a mail-order calibration, so you are required to send DTE your PCM for the upgrade and turn-around time is only 1 day from the time we receive your PCM. Return shipping from DTE back to you is INCLUDED in the price and all outgoing PCM's from DTE carry full replacement shipping insurance.

Stage II Performance PCM Upgrade- $299

Orders can be placed by calling the office at (260)407-5455 anytime during regular business hours and if you have a specific questions about this, or anything else, please contact me directly at ext. 11. Thank you gents and happy motoring.

Not yet, i'm ordering off Modern performance stage 2/3 injectors.. A boomba fuel rail wont effect the way its running will it? Also, not 100% sure, but will the mopar stage 2/3 injectors hook up to the RC wires?
