Without seeing what you are doing in your tune and a datalog it can be anyone?s guess as to what?s going on. Make sure in the datalog you are including PIDs that tell you the correction reason for timing and fueling, these help narrow things down.
I'm referring to the boost limit A table under main injection limits it was never changed
so basically my total fuel rate is being defueled due to this table from what I'm understanding do people normally just turn it off or adjust the table accordingly
I guess my point is since you are falling flat right at redline, which has tons of limiters, what is telling you that you are hitting the boost limit as for falling flat?

so i guess when the shop did the tunes he missed some of the limiters past 3k? if so what are some things that i need to change? that are not going to hurt my stock motor
i attached the main soi timing,inj pulse, and boost limit a Attachment 106708Attachment 106709Attachment 106710Attachment 106712
i also attached a log file to show what im talking about it you go to timestamp 06:51:48 that was 2nt to 3rd locked up, and at timestamp 06:52:38 that is a 3rd gear pull locked up
im running a stage 3 FMVB trans with lockup switch
What rpm are you trying to run up to?
Yes the tune is pulling fuel back through that table, you can raise fuel limits in that table or you can bypass the table with the override that's enabled by changing the 0mm3 below the switch to a value above your max commanded fuel quantity. If you log correction reasons it will tell you when you hit a limiter and what the limiter is. As for anything else that could be restricting fueling above 3200rpm, couldn't tell you cause I can't see.
The truck per the tune is unlocked till 4k obviously I wouldn't need it and rarely get that high max I have gone is what you see there my plan is to make this into a drag truck eventually so I'm trying to learn everything I can now
What would be safer just bumping the values up or just disabling the table all together
Just raise areas up till you like it, but again, there are other limiters that could be there.
Okay thanks for the help seriously , Is there any layouts that you can download for logging or do I just have to manually add them one by oneQuote:
