Bay State Garage down in West Dennis for me. His name is Bill too (also like me, haha). He's had the opportunity to screw me over HARDCORE many times on my '97 F150 and '98 Mountaineer, and never has.

Local ftw!

Not really, just google "hennessy lawsuits".

In any case, it is important to treat each car in its own unique way.

I also feel that name brands have something more to uphold than local shops. As a result, I will probably be taking my Camaro to someone big.

just remember that a big name doesn't necessarily imply a good job will be done on your car... for instance, MTI in Houston was one of the biggest LSx shops in the US for about a 5 year stretch... and I have personally fixed at least three of their tunes... and those tunes were done on a DynoJet dyno at the MTI shop... sometimes things get busy and those big shops will rush a bit on one car to make another car they know is going to be difficult get finished before close of business.

and there are things that you can get a tuner to do that dont require a dyno... tuning out the speed limiter, removing CAGS, recalibrating the speedometer for bigger wheels and deleting torque management are all things that can be done to a car that will not require a dyno.

Close...Magnuson-Moss.

They can't void your warranty no matter what, but they can deny a specific claim, if they can reasonably argue that your modification directly caused the problem. The warranty remains in effect. In reality, it could get messy if they want to blame your modifications and don't want to cover you. You gotta pay to play and risking your warranty is part of modifying a brand new car.

Ummmm...I think you need to examine GM's warranty very carefully. Also, the Magnusson Moss Act is not worth the paper its printed on as it is full of "loop holes." In the "real world," YOU have to prove that the aftermarket addition or replacement did not cause the failure.

The following relevant material was posted over at smokinvette.com

If GM finds an aftermarket tune (and they are instructed to look, and if they look I promise you they will find it) it will void your Powertrain warranty. GM has adopted a very strict position on aftermarket tunes. If your car has anything but the factory calibrations and they find it, kiss your powertrain warranty goodbye. Real simple, you want to play, you have to be prepared to pay.

Here is an excerpt from GM's instructions to dealers on aftermarket tunes:

Here is GM's official position on aftermarket software changes.

#PIP4386: Identifying Aftermarket Engine Calibrations - 2.0 2.2 2.4 2.8 2.9 3.0 3.1 3.2 3.4 3.5 3.6 3.8 3.9 4.2 4.3 4.4 4.6 4.8 5.0 5.3 5.7 6.0 6.2 7.0 7.4 8.1 - (Apr 8, 2008)


Subject: Identifying Aftermarket Engine Calibrations


Models: 2005-2009 GM Passenger Cars and Light Duty Trucks

except Pontiac Vibe, Chevy Aveo, and All Saab Models




--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
A dealer may have the need to verify engine calibrations. If a dealer feels an aftermarket power-up calibration has induced engine and/or drive train damage, there is now a way to verify what calibration is currently in the vehicle.

If a suspicious hard part failure is observed in the engine, transmission, transfer case, or driveline, perform the calibration verification described to determine if a non GM issued engine calibration is installed. Non GM issued engine calibrations subject driveline components to stresses different than those that these components were validated to. Repairs to transmission, transfer case and / or other driveline components where a non GM engine calibration has been verified, are not covered under the terms of the New Vehicle Warranty.

Recommendation/Instructions:
Instructions for confirming Calibration Verification Number (CVN)
• Go to TIS2WEB

• Select Calibration Information (SPS Info)

• Enter VIN

• Select "Get Cal ID"

• Select ECM Engine Control Module

• Hit "next"

• Select "Complete History"

• Print

Take Printout to Vehicle along with Tech II
• Plug in Tech II

• Go to diagnostics and build the vehicle

• Select Powertrain

• Select the engine

• Select F0 - Engine Control Module

• Select F4/F5 - I/M information System / Module ID information*

• Select F1

• Compare the calibration ID and Calibration Verification Numbers (CVN) to the Calibration Verification Numbers (CVN) on the printout.

* This step may vary by controller; use the Module ID Information in the Engine Controls.

Although the part numbers will be the same for each, it's the CVN that will determine if the calibration is GM issued.

If ALL of the CVN's are EXACTLY the same, the calibration is GM issued.

If the part numbers match and ANY calibration verification numbers (CVN's) do not match the printout, it is likely that a non GM certified calibration has been installed.

In order to document the case - a CLEAR digital picture should be taken of the TECH 2 screen showing the VIN and the CVN's that do not match the TIS2WEB printout. The picture and a PDF copy of the TIS2WEB printout should be forwarded to ***email edited***@GM.com for verification along with the VIN and the reason the vehicle is currently in for service. Please copy your GM Area Service Manager (DVM/DSM) on the e-mail. GM will verify if the CVN's are not GM issued and respond via e-mail within 48 hours.

If both the Part numbers and the CVN are different, photograph the part numbers and CVN's on the tech 2 screen as described above, assuring the VIN shows clearly in the photograph of the TECH2 screen, and check to see if the vehicle has the latest released calibration. If the latest released calibration is not installed in the vehicle, the part numbers will not match , and the CVN's won't either. E- mail the original Part Numbers and CVN's found in the vehicle on the TECH 2 to: ***email edited out ***@GM.com to check if the calibration and CVN matches a previous release. Recalibrate with the latest released cal and re-check against the part numbers and CVN's that are released.


Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
