Default Anybody here burning chips?

I need my Memcal copied and a new one burned deleting EGR and MAF burnoff relay.
And.....maybe lowering the max auto trans shift point to 4700rpm.

I have had great luck with Alvin at PCMofNC and they are a supporting Vendor.
You didnt mention the year of your vette, but unless it is a 94 or newer I dont think shift points are controlled by the computer.

If you want to change shift points, you will have to play with the governor. There are calibration kits available.

And in an attempt to "nip it in the bud", if someone tells you to fk with the TV cable, ignore them.

Thank you for the info. I forgot the 700-R4 is not computer controlled.

Probably something the mods need to worry about - not us. If needed, they will do what they are getting paid for. In the meantime, any noted information can be of benefit so someone.
