Ran attached tune with log file results drives fantastic but still has initial startup idle fluctuations.

Ran today with attached tune. Used components from L96 Express idle and airflow to test effects on power and startup idle. Start up was idle was still fluctuating but at higher RPMS so it didn't dip...

The initial file was a mix of the Texas tuner co. and a local tech that knew enough to keep the check engine light off. The file I used that had good power was a repository tune that had all the...

Thank you had no idea about advanced. Now I have a lot more items to compare. My original file that you modified with the correct injectors has a very smooth startup and idle. The file I had in...

I dont see where the fuel data chart is. When I compared the original file with the same file with injector dat you added. I couldn't see differences in compare. There seems to be about 100 new...

Was there ever a solution found to this surging idle issue?

With the help from the contributors of this thread and info from a repository tune my truck is running fantastic. Please see my current tune and advise if I may be overlooking some beneficial...

When trying to use parameters from a repository tune, the file cannot be loaded unless I have a license for that tune, correct? The repository tune can be viewed and compared and my tune file updated...

I have registered my MPVI3 and my account shows my 2 credits. But I cannot find how/where to apply the credits to my device so I can write.

I recently bought MPVI3 and 2 credits to tune my 2013 Tahoe with an L96 (6.0) conversion. I dont want to get caught up buying more credits than necessary to work on my vehicle. I assume my credits...

The fuel injectors on my 6.0 are PN 12613412 other numbers on them 5033A and RB4. I dont know if the 6.0 would run on the 5.3 injectors, but if it would, and it would make my tuning life easier I...

Agreed stock is insufficient terminology. The 6.0 was complete intake to oil pan. I will research specifics like fuel injectors, as the need presents itself. The 6L80 transmission and everything else...

New to everything vehicle computer / tuner related.

I have a 2013 Tahoe that ruined the 5.3 in 2020 due to the AFM system failure. In a quest to get better power and eliminate the AFM, I swapped...

I don't know how to use HP software, so I'm assuming the answer is yes, copying over. As far as I know the 2010 Yukon with a 6.0 would be a Denali, which would also mean it has a different...

I have the ability to put the computer back to the stock tune at any time to get the computer to a base line, however the 6L wont run at all on the factory 5.3 tune. So whatever changes I attempt, I...

I am new to this forum and hoping someone will have some helpful tuner information. I have a 2013 Tahoe that experienced an AFM failure resulting in sever engine damage. To correct this I swapped in...
