you can add fuel in your "PE modifier based on RPM". if your fueling is good at 4500rpm when the maf is maxed out then you start adding to the numbers in the pe/rpm table at that point. a good rule of thumb is to add 3% to each cell from 4500 up. from 4500 up your fueling will be based on this table only and will be almost entirly rpm dependant. with a wide band it isn't hard at all to dial in your fuel even with the maxed maf using this method. if your still a little lean then try 4% per cell and if your rich try 2%.

NOW HERE IS THE PROBLEM WITH THIS METHOD. you can get your fueling dead on for a certain day/weather. if it is 30deg cooler the next day you will max the maf sooner and the extra fueling you just programed in wont be enough. if it is much hotter than you will end up rich. in nebraska our weather varies 30deg in one day often and the highs from one day to the next vary 30deg day to day so this didn't work all that well for me. the sooner you max out the maf the more you will be guessing.

i dont know much about the 2bar or 3 bar stuff. do they have the 3bar stuff working?

With the 4l60e and 3.42s I would hit full boost in every gear. Maybe with the 3.73 the turbo is not getting enough load. This is very common with 6 spead guys and higher geared ratios.

THanks, I have just talked to a few guys today, they say I have to do a second gear burn out with the streets. I am not getting them hot enough. I think I will up the two step from 3900rpm to 4500rpm. I think I could get more boost off the line. Before I go again, I will have some sd tunning done 3 bar. I talked to rick (@ synergy)today and he says he can do 2 or 3 bar whitch ever I wanted. So 3 bar it is. The softwear that came with my digital camera is not working well with my computer. I will play with the softwear later, I have not had time to play with it...

Congrats on hitting 12's. I'm happy to see you getting closer to the results you built it for.
