not sure if your wideband input is reading right
i would have is around 12.3/12.5 AFR

may be safe in 6th gear full rpm...maybe 7th too..i have a 2 mile challenge..that i can work on to improve
the confiability
thank you
in the penultimate acceleration kr is seen ..
for what reason can it be?
thank you
dyno data
575 hp @ 5680 at wheel
fuel 93
thank you[/QUOTE]
11.9/12 afr is good and safe
any other channel to pay attention?Quote:

lowering spark advance will keep the chamber cooler?
Thinking of keeping a little cooler
thanks for your reply
Wait, you're going to run this thing WOT for 2 miles on 93 gas? On stock LT1 pistons/rings?Quote:

Test in 7th gear... so as not to exceed the pressure... up to about 5500 my car registered
a speed of 189 miles from gps .. it was more for security court ..
Why doesn't it generate more hp...continuing to increase pressure?
What can I modify in my melody to take advantage of the psi?
improve fuel octane
THANK YOU
when I install the pulley for 7 psi, will it generate the same hp? at more rpm?
Will I have to change my melody?
correct airflow?
thank you

log and corresponding map
kr problems .. this map was installed before acquiring the car
the required pump pressure was only 2350
maybe there could be a reason why it was configured that way
I remember that the car has a complete lt4 upgrade
secondary cat removed
faulty wideband
previous map with more pressure less kr
makes sense?
@grcam6 is right, 10 psi is too much on a stock bottom end LT1 on 93 octane gas. I would pulley to 7 psi if you’re going to run the car hard.
thanks for your advice..Quote:

No since you’re lowering your boost. But you would want to check MAF scaling if you were raising boost (inadvisable in this case).
thank you!! your information is very useful
when I install my pulley I will have more news
sorry for my English
learning the language
I am from Argentina
No problem, happy to help.
