Those are really cool downloads! I'll have to log on my computer to read them. What kind of device are you using? Impressive!!

Your running higher boost and lower charge temperatures then I did on stage 2. But, you have more ignition correction.
I added a little ethanol to my fuel to eliminated ignition correction. I started by mixing a small amount of ethanol to my gas and am now running E20+ on an OTS 93 octane stage 3 tune.

Hey, I'm sorry, you're right! My ECU was pulling timing due to high charge temperatures And I started getting knock with stage 3. That's when I started mixing my own fuel.
But you're stage 2 data is still more aggressive then I remember my stage 2 being.
Did Cobb make changes to their OTS tunes after eliminating OTS 3?

When you say "some own modifications"... Do you mean modifications to your Cobb map??
First my cobb dont come with the stage 3 map and i arranged the pedal percentage to my liking to vary the afr at low rpm the car doesn't go so lean before the car would enter aft target i had to accelerate to minimise 50% of the pedal i put it at 20% and fix the afr target to 3000rpm i did the same with the Vtc so they could work

Sorry but my english its not very good im dominican

You must have the new Cobb tuning device. Glad they upgraded stage 2! This gives you a better value without having to change your catalytic converter. Plus mine isn't adjustable unless I upgrade and get certified.
