L5P Turbo Vane Position Tuning

[mm_n_p]

Installed an aftermarket turbo that I have running fairly well but very laggy under 1600 rpms, With that, I noticed its not reaching desired boost so I experimented by closing vanes 10% in that area and it responded well.

Truck has a SOTF OS in it and haven't really had to bother with vane position much so just curious where a good place to start is.

And one more question while I have you..what is the barometric value for determining when the Low/Med/Hi alt tables are being accessed?

Thanks anyway guys...I found my answer messing with it myself, completely different truck below 1800 rpm now. It was a slush box until the light switch came on between 1600-1800 rpm, now its a tire smoker from a roll and turbo stays spooled up better in low rpm areas.

Now to figure out a way to dial in the MAF a little closer.
