Upping the boost...Where do it tune for this?
Upping the boost...Where do it tune for this? The car has been tuned for 13psi. Is the power enrichment the only place i need to go to add more fuel when i up the boost or where else should i go and adjust for this? Thinking as high as 20psi maybe (or where my injectors will let me go: they are only motoron 65lbers).
This is a turbo car by the way

boost If you're running SD with a 2 bar map (or 3 bar), ve tables "vs" map.
On mine, I ran a 2 bar sensor, so when I began to go into boost, I started adding in the ve tables from 50kpa to 75 kpa. ( I only ran 6psi) 50kpa was my new atmospheric measure, 75kpa equaled to 6psi.
IF I were to go on up to 14psi, the map would have measured above 75kpa, and that's where I would have had to add more to the ve tables.
Hope that helps.

You MAF is likely maxed out by 4K! I know that mine is on a similar setup..
What you are doing is no way to run a turbo car. You can cheat PE and get the AFR right today, but it won't be the same tomorrow, and so on. From warm to cooler weather the change in AFR will be large. If you tune it on a warm day (80-90) in maxed MAF PE, and then take it out on a 50-60 deg day watch your WB like a HAWK. The variation could be a full point or more at your power level.
Also don't forget to trim the timing back.

Why not just run a custom OS and have the VE and MAP sensor agree?
