Ok i need to know what to adjust in HP tuners to add more fuel from 5600+, i know where all the tables are and sort of what they do but no idea how to adjust them, based on this data and shooting for an AFR of 12.0 or lower what would you change?
Through looking at all the Data logs it looks like the cause my knock retard is a lean condition when my AFR reaches 12.2 or Higher under 100 percent TPS the knock begins. Interesting though that after 6500 the car starts to richen up again. Heres what my AFR looks like, talk about a linear curve

post your .hpt file
I looked at a 2003 in the hope of seeing a decent PE table and there isnt one.
There is a PE onset delay which was set at 6k on the 03 stock cal, lowering that could help.
You can also adjust the High RPM VE table at those leaner points.
sig not found
my PE delay is set to 5600
What do I adjust in the high RPM VE up down? what percentage?

Holy crap, my PE delay is set to 2800, it was 3200 stock, I'd think you'd want to have it in PE a lot sooner than 5600...
You need to make the VE tables go up in percentage, it needs to know there is more air, so it adds more fuel.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
well i can try moving the delay down but i doubt that alone will fix the problem
Ill try making some very small changes in the High RPM VE and see how the afrs are

go through your data log file and at those rpms you stated above, write down what your map signal was. Go into your High RPM VE table and change only those cells. Higher number = more fuel and lower number = less fuel.
well since I have a stock one bar map sensor its pegged at 103kpa from about 3000rpm up so i cant really do that
