map recommendations?

[garyk1970]

I've got a 2000 Silverado with a turbo 4.8. Cos3 SD . what map should I use? I bought a new zr1 3.5 map and my tune is very rich...strange it will run decent in first gear only.. 4l60 auto... Eventually target boost psi will be 20..

Did you set the MAP sensor scaler/offset (so that KOEO MAP pid shows BARO)...?

[garyk1970]

No, I don't even know how to data log yet... I talked to a tuner and I was told the map I used has been know to not work good with my setup.
I did set map to 288 .....
Thanks for the help, Ive been searching and reading , its a lot to learn quickly.

Yes, post it here.

I'm running behind since we got my wife's Dad in the hospital, I'm trying to squeeze everything in between room visits and meetings with doctors, so it will take me a couple a few days (please bear with).
