If your tables are slightly higher than needed and you let it downward correct ever so slightly - no... it will still do what you want and be pretty flat. Fine line though. I mean a LITTLE higher on GOOD dialed tables. Before anyone throws a hissy fit about what I just posted. I'll try the TPS portion. Bryan knows his ecu boost control. He's been doing it a long while in great volume.

Yup I hear ya, I have been using ecu-controlled-boost for almost two years and its always been 'pretty flat' ....my point is that this gear-based setup is taking 'pretty good' and making it better; evolution, or a new milestone in a long line of small amounts of progress, if you will

Scheides very good job I know this is an old post but I just found it. I think my Christmas present to myself will be GrimmSpeed 3 port Solenoid(my tuner used on on load based boost and now prefers it over Pierburg and GM 3 port), Omni 4 bar MAP, Tephra V7, and MrFred....btw your boost curve looks nice and smooth love it!

I have a little 16g TME', a 2.0, mild cams and stock muffler. This gets me a quick spike up to 21PSI @ 3.5-4K in 3rd and a nice plateu all the way to 6k and a taper to 19. All gears have a similar profile.
Probably not to different if you have a stock-ish set up. And yes it ****ing rocks!

What I did was take a log of each gear for at least 3 seconds, then divided avg rpm by avg speed. Say for instance you get an average speed of 35 mph and average rpm of 4000 while making a pull in 3rd. (4000/35 = 114.286) So now you'd input 114 into the 3rd gear row.
BTW: I copied the value from 5th gear for 6th in an attempt to fix an issue, and copied the 1st gear value into 0 gear row to allow for full boost when using the launch maps.
