This site says they have a chip that will increase performance by 50 hp and 50ft-lb of torque and at the same time increase mileage by 3-6 mpg. They only want $69.99.
I think it is a bunch of rubbish. If it was as simple as $70 to get that much more performance at better efficiency, GM would be using that chip. This falls into that "it's too good to be true" category for me.
im the idiot who purchased one of those "chips" :banghead: it was nothing more than a resistor, sure, now they are fancy connectors and boxes, but that is all they are. plus, you really only get those increases when the conditions are right, ie. barometer, temp, altitude.
Not sure if it is available or not for the Acadia, but I had my PCM tuned in my 2002 Silverado and it made a huge difference. I had it done with Wait4Me Performance. Cost me $157.00, best money I ever spent. I guess I need to call them and find out if they can do our Acadia's. If anyone is interested as well their web site is http://www.wait4meperformance.com/
I just thought I'd throw this out there to chew on. I'm not trying to make any statement for or against: ;D
#08-06-04-033B: Identifying Aftermarket Engine and Transmission Calibrations Gas Powered Engines Only and Automatic Transmissions - (Aug 26, 2008)
Important: This bulletin applies to Gas Powered Engines ONLY. For Diesel Powered Engines, refer to Service Bulletin #08-06-04-006A.
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 the calibrations which these components were validated to. Repairs to engine, 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.
If a non-GM calibration is found to be in the ECM or TCM (CVN's on the Tech 2® do not match TIS printout) - In order to document the case -- a CLEAR digital picture should be taken of the Tech 2® screen showing the VIN and the CVNs that do not match the TIS2WEB printout. The picture, VIN and reason the vehicle is currently in for service should be emailed to * for verification. Please copy your GM District Service Manager (DVM) on the e-mail. GM will verify if the CVNs are not GM issued and respond via e-mail within 72 hours.
