It was a feature of the GMPP tune, although others may have adopted it. I recall Trifecta saying that some had asked for it, although I can't really see ever wanting to use it, myself.

Satdpc Hmmm.. I don't know if I could get used to the "No Lift" feature. Racing Formula Fords for over 26 years I shift with the "No Clutch" technique, only blipping the throttle. Completely backwards.

Nope - the factory GMPP tune was popular during the warranty period but once that passed, there are better tunes producing more power for far less money. No surprise that few are doing much with GMPP these days.

Very nice mph! And only a tune? On the trifecta in good air I can only hit 80-81mph in the 1/8.

About the same for me. Same tune. But when the weather cools we go faster!

So what was your 1/4 time?

I have a auto with only a tune and nothing else. On a cold day 55-60 degrees with a good 1.87 sixty ft ran 13.29 @ 101mph.

Normal it is usually around 13.60-13.70

GS Stage 1 Every car is different and altitude does make a huge difference as well. Also you will notice that peak boost goes higher with each gear. This is an electronically controlled boost system that commands boost based upon several conditions. 19-23 PSI at sea level and 23-27 at 5000 feet above sea level are good general guidelines. But they are all different.

380ss After reading all of this, I would like to know what boost we are suppose to achieve with the GMPP upgrade. I've seen 23 lbs mentioned here and 19. I currently get 19 but I'm at 900ft above sea level. Does that matter?

I should also mentioned that I hit 23lbs once but the car recently threw the code that everyone talks about and I had it in the shop to get the wires soldered to the map sensors. (They came loose)

GS Stage 1 I have the GMPP tune:

If you have any wheel spin at all, credits roll on hitting 60 before you bounce off the rev limiter in 2nd.

If everything is perfect, you can just barely hit 60 in 2nd. But in practical application, I am usually shifting into 3rd by then.

Also: You may want to check it against a GPS of some kind, because the speedo and tach are both a little slow to react in our cars.
