    Just a quick little update on this thread, I installed the LT5 throttle body and just got done tuning the VVE & MAF. Had to fight with a torque tables around 5,800 RPMs but it is now running stronger than ever.

    Those E85 changes made a tremendous difference. I updated my buddy Sierra with the same changes and it turned his truck into a different animal as well. I appreciate you guys for all your input. Little by little I'm learning how to work this software.

    Oh man! I've been very distracted with Ecoboom vehicles lately and did not see this thread until today. Really bummed that I am too late to see the 8L90E mods GHuggins made. Would love to compare to them and learn more.

    It was a 6l although you can make the same changes to the 8l, just a whole whole whole lot more tuning involved at that point... Think I mentioned them or at least how I do them in an 8sp thread in the transmission section.

    Thanks so much for your response. I've spent a lot of time learning the 6l on 4th GEN and pretty happy with the results but I'm sure your input would bring much more good. Thanks for making the HPTuning world a better place!

    I have one last question you guys may be able to put to bed for me...After doing another full tune from start to finish with the new Throttle Body, I thought I would get rid of this therefore I never mentioned it in the original post but you can see it was there. I increased and decreased virtual torque for those areas and neither adjustment seems to rid it. Seems like it is only occurring in the first gear but does not appear in the remaining gears under WOT. Is this an anomaly that I must just understand to be an issue or can it be adjusted?

    This is only happening for .2 seconds therefore you do not feel it but is bothers me seeing it on the log.

    Usually in the main spark tables - another table getting mixed into for example or an area that needs smoothing, mbt table as it'll be used for peak torque timing calcs or some rationality check going on - no one solution and honestly other than checking those, I'm not sure I would worry about it. I would leave the torque model how it was for your shifting and everything.

    Everything about it seems fine and it moves fairly well for such a big girl.

    I looked at my MBT Corrections table and the entire table is set to "5" by the last tuner that touched it. Should this be set just as the stock tune has it? Stock tune has it all as negative numbers whereas my current tune has it all at positive 5 degrees.

    That sounds like the min spark table. The mbt table is this and it typically is at or above the timing your running

    For example if I copy with axis my main timing table and then paste it into the mbt table you will see it's about 4 or degrees higher than my main timing table. This one also shows an area I need to fix after the last timing changes.

    Thanks man! The one I adjusted was the Max torque timing Alcohol Adder. Adjusting that did not change anything so I'm looking into this one now. So it should be about 4 degrees higher than my High Octane spark table??

    Appreciate the input.

    I looked at the High Octane timing and MBT and they are off significantly. Not seeing any limitations as the MBT is a bit higher than my total timing with E85.

    Posting current tune and last log. You only see this happening in 1st gear at 5.900 rpms. Maybe I am chasing a unicorn with this?

    I see the changes, trying the torque management upshift torque factor first and then will add the other changes for shift timing but I don't think that'll make any differences as I already adjusted those parameters with no changes. I lowered the shift speed and RPM and still was present. Didn't think about the torque factor! I'm going to make minor adjustments to see if it fixes it. If it does, I'll slowly step the torque factor back up until it appears again to find the sweet spot.

    All this is so helpful to know what these changes effect rather than just telling someone to set this to that. Knowing what it does helps with the understanding of it all. Sometimes hovering the mouse over the tab does not provide a ideal description on what that parameter effects.

    ***I also added the changes for your transition times as well***

    Well! I must say this truck is running absolutely perfectly therefore I must move on. My wife done gave me money to install a Twin Turbo kit so that'll be happening within the next month. When I had the ProCharger, I used the Vette/Camaro (cannot remember which) MAP sensor and it worked with no issues but not sure if the same is true for a Twin Turbo...Is there a difference?

    Please lemme know!

    You have to do the breakout for the baro in the MAF.

    You better hold on to her

    Will my stock MAP sensor read a 3 bar or do I need to get a MAP from a CTS-v or ZL1?

    With my ProCharger, I used a CTS-V MAP sensor but it went with the kit when I sold it so I am using my stock MAP sensor.

    You need a map that will read boost such as the zl.
