I emailed Ulmer about this header last night and he stated and there is a post on here somewhere that he did extensive dyno test this year with MBRP, Straight line and EVO and the MBRP had no hp gain over the stock header. So unless you want a $400.00 thing of beauty where no one can see it save your money.
I know the EVO header makes power

I saw the agreement in the PCV software to allow rev extend. Once agreed to, does it present a settings box to set what you want to limit to?
I think what you are referring to is the rev limit? If that is your question....when they send you a code, you can only go over your stock limiter 500 rpms. (But, after calling them and telling them what I was doing they sent me a special code that went to 10,000 for Shagman's sled)
If you are asking about the launch control with the module, then yes....you can set that rpm for your launch rpm to hold while holding the button.

You must send in the serial number from your PCV in order to get a rev extend code.

Thanks Allen. I'll be calling you in a couple weeks for an autotune at minimum and maybe an ignition module. May hold off on the ignition module till mid season.You must send in the serial number from your PCV in order to get a rev extend code.
