2004 & 2005 Northstar Tuning (front wheel drive)

Cadillac Seville, Cadillac Deville/DHS/DTS, and Bonneville GXP

$499 for the tune, $629 if you need it flashed to a core PCM





     We are ready to tune your 2004-2005 Northstar PCMs! This is what you can expect:

      -Improved Performance and Acceleration
      -Improved Throttle Response
      -Better Fuel Economy While Cruising
      -Speed limiter removed and rev limiter raised
      -Ignition Timing Remapped
      -Fuelling increased during acceleration
      -Torque Management Removed
      -P0420 Code Taken Care of for those off road applications
      -Increased Shift Firmness If Desired.
      -Raised Shift Points at Wide Open Throttle
      -Tire Size Change / Speedometer Correction

If you send us your PCM for re-flashing it will be Plug-And-Play when you get it back.

Use the mail/postal service to send PCMs to the following address:

Northstar Performance
890 Fairground Road
Langton, Ontario
N0E 1G0 Canada

You MUST mark a value of $10 on the box and mark down the PCM is being sent "FOR REPAIR".

We can also send you a good tested core PCM that we flash to your VIN. If we do this, you will need to do a key learn procedure which most of the time can be done in your driveway with nothing more than 30 minutes of your time. You will need to have a good scan tool or visit a local garage to do a crank position re-learn procedure which takes about 10 minutes. Canadian Cars and overseas (Europe) need to have the key-learn procedure done at a GM dealership or a garage that can service GM vehicles.

Options

PCMs will be shipped out from our shop using DHL Express. If you absolutely can't afford to be down a vehicle while you wait for tuning, We recommend just purchasing a flashed PCM that we supply.

Installation can be done by anyone who can operate a screwdriver and follow basic instructions. If that statement scares you, have a repair shop install the tuned PCM for you.

***NOTE*** As this tuning service is new on the 2004-2005 PCMs we reserve the right to test for up to 15 days after payment is received before we ship. We have various 2004-2005 Northstar cars here we can and do test with. We want a solid product for our customers and this is the reason for the time delay. Also, if we can squeeze more out of our tunes later on, we do reflashing for only the cost of shipping for all 04-05 tune orders placed before December 31, 2020.
