I am still getting the P0171
Another thing too: The oxygen sensor reading on evoscan seems to go to 0 here and there. Either this is a bug in the software on it's possible I have an o2 sensor on the fritz.

Car pulls smooth and hard.. way better than before. I'm going to try to dyno again @ BR July 7th. Hopefully I can get two hours of time so I can swap gas/maps and get some good data on my car
One thing on the timing. Do you think tapering the idle advance might help idle out some?
My "base" flash increases with load.

From the maps that I've seen those seem like pretty aggresive timing curves on pump gas.
Ummmm...how are you trying to tune with a destroyed MAF sensor?

Here is a map to start with
This map is fron a 2003 that has the following mods
GSC cams 272 set at -2/-2
Precision 680 cc/injectors
no cat
TBE
10.5 hotside
Ebay Turbo outlet
AMS FMIC
stock air filter/box
93 octane
MBC Forge
entire map is scaled to 325 load. However, it has only been tested to 21.5 psig (<280 load)
Note: Immobilizer code is set at "0000" .......you will need to change it to your code
Use at your own risk....but it should be close enough to eliminate most of your problems.
Anyone can feel free to comment on it

That could be it. I know it goes to 21 AFR which is the leanest my wideband reads. I would like to get rid of the P0171 it's pretty annoying.
I'm going to get a new maf as soon as I can find one that's perfect I've been missing the honeycomb for some time now with no serious issues.

Correct me if I'm wrong, but the MAF will not work properly unless there is a honey comb in place.

what tools did you use to tune your car? Did you use the dyno or street?

Street tuned
PLX wideband and ECU+
According to the ECU+ dyno 285 tq at 4300, 283 Hp @ 6700, 0% tranny loss, 3600 lb car
HiVolt
Note....ECU+ plus set at zero correction
