OFT : stage 2 and stage2+ what is the diference
 

any one know what is the diference with the
stage 2 map and stage2+ map

2 = Aftermarket catted header
2+ = catless header

My OFT came with Stg-2-Plus-E85-v4.03-Z** but I have Stock EL Headers but my Second Cat in the front pipe is removed. Can I run this until I get a custom tune?

Only if you are actually running E85, then yes.

You can download the files to get the appropriate tune for your set up on the OFT site.

What is your setup? Why do you want to run the tune that came on it?

Yes sir, I downloaded all my off-the-shelf BIN's from the OFT site. I had noticed that the only E85 tune that came with it was Stage 2 Plus. I think that after a certain OFT Version that the E85 tune didn't matter if you had cats or not, it would work even though it's Stage 2 Plus.
I want to run it even though my headers are catted.

Additionally, I could have just check the OFT website again lol:
