[Number 3]

GM could do this and I hope they do. I had the GMPP calibration in my Sky Redline and it was a very noticeable improvement.

It's not difficult to do this and some will ask why this isn't stock. Well it's cost for one and 2nd the failure rate will go up on a stock engine with increased power. So you then have to increase the cost of your content to a higher level to handle the added stress.

But a unique higher performance calibration can be developed with out a huge amount of work. But it is work and it would require testing and validation.

So would you pay $2,400 for a warranty covered 40 HP? I might if you can roll into the purchase price.

This is will be a limited market, but we'll see if GM responds.
