    Once it's sorted out the truck with Pat's tune will run the number.

    As Jody suggested, do some logging to verify that the pumps are working properly and it's holding rail pressure...

    I run a stock LBZ cam to 797rwhp at 4400 RPM peak.

    I could push it higher, but there are other limits we need to work through. It's not the cam.

    It can now be programmed out, and does not affect all vehicles.

    Just email Kat your tune with a letter stating when you bought the tune, and I will fix it.

    You did buy it from us, right?

    And yes, there are alot of LBZ's running 12's on the Wendy tune.
    Pat,
    Brian (hondarider552) does not own EFILive (yet). He has PPE, and is looking to go with EFILive. He was very curious about your race tune so I loaded it for him and let him run it at the track. I got the tune from you at the EFILive class I attended. At that time, you told me I could share your tune (in the manner described above) so long as credit was given where credit is due. I did not alter the tune what-so-ever and Brian knew from the beginning, this was your tune, not mine. I hope your feelings on this have not changed, but if they have, let me know and I will not load it for Brian again. He does not have the tune itself, I loaded it for him and subsequently tuned it back to stock so he could continue to use his PPE tuner.

    At any rate, when I first got the tune from you, I loaded the tune in my truck and it was exhibiting some similar behaviour to what Brian is reporting. At the time, I already had a tune I built myself that I prefered as my daily driver so I didn't look any further into your tune.

    With that being said, if you want to continue to help Brian figure out what is going on with your tune, I'll email you the copy I have. It's the one that you gave out on the memory stick at the EFILive class.

    Thanks,
