What pcm are you using for your project.
If it is ,05 or later you may be stuck using HPTuners to tune. P01's and P59's have much more open source support.

Slightly off-topic:
L33s came with 'LS6ish heads' without the LS6 valvetrain yeah - the 799 casting?
706-casting heads would be a cheap upgrade.

If you already have better heads, disregard.LM7, L59, LM4, & L33 all used P59.

[QUOTE=87stepside;89885]i have a 4896 p01 im planning to use, however its 9373372 OS so i'm pretty sure i need to swap OS to 12212156 or whatever is best. }
If you engine came out of a '05 it should have a harness for a P59.
Personally I would use a P59 with the '7603 OS which is more versatile depending on if you are using DBW, DBC, etc! If you are using a carb and just using the PCM for timing then the P01 would be fine. There are so many combinations that work well it is always interesting to see the solutions that come up.
The plugin being referred to can be found here:

I believe it was included in the last version of Tuner Pro RT, but I had already installed the plugin previously.

Here is a stock L33 (5.3 4L60E) with factory 4.10 gears. out of 06 Silverado. this one has 243 heads on it. the computer is newer but maybe the maps will help. Has factory electric fan settings.
rickky bobby, that is a 1263246 OS for a P59 (1mb ECU). The OP has stated he plans on using a P01 ECU. Your OS and related maps will be useless to the OP. Also, there is no .xdf available for that OS to use in Tuner Pro, and even attempting to use maps from it will totally mess things up badly!
