Hello everyone. I've been hard at work lately on 2006-2008 3800 Grand Prix computer tuning
As most who own an 06+ 3800 Grand Prix know, you have non reprogrammable PCMs. At least, you didn't.
I'm very excited and pleased to post that I'll be offering a proper tuning solution for 06-08 GPs using your original PCM modules. What this means is:
-no more searching for 2005 PCM modules
-no more non-returnable computer cores
-no more extra expense just to make your vehicle tuneable.
You'll be able to purchase an Overkill PCM tune, receive a 06+ PCM module that's been reprogrammed, and send back your old module for the core charge refund.
Also, 2007-2008 owners, you'll be pleased to know that I've been able to correct the operation of the fuel gauge on your vehicles with an aftermarket tune, so when you purchase an Overkill PCM for your 07-08 you'll receive a PCM that won't cause your fuel gauge to read backwards.
All of this announcement is exclusive to Overkill Motorsports. I've worked very hard lately for 06+ owners to provide better tuning solutions.
If you've purchased a 2005 based Overkill PCM for your 2006+ vehicle in past, stay tuned, I'm going to see what I can work out to allow you to return your 2006 computers for at least a partial core charge refund regardless of when you purchased. Please email me willoverkill@gmail.com if you'd be interested in this.
My website will be updated shortly with the changes! :: Overkill Motorsports ::
Any questions please post or email.
