Getting ready for 2 bar sd and supercharger install

[rjw]

I am going to install a magnuson sc on my 03 vette.

I have the 2 bar sd os

In following the basic instructions i.e. copying my current ve settings into the unboosted part of the new ve 2 bar table, I have my first question.

Does anyone have a sample or can recommend what values to use in the boosted areas as a starting point?

Something obviously rich, but not beyond being able to run.

car already has haeds, headers, mid size cam,etc.

Any help would be appreciated

Thx

i don't believe a 2 bar OS is really necessary for a Magnuson. And it way easier to do a Maf tune. What are your cam specs? What CR do you have?

cam is lg G5X1...228/232 .578/.570" heads are afr 205's and headers are kooks longtubes.

Initially I will attempt oem maggie setup and from there, I will be adding WI, 90mm snout and other pulley combos.

Eventually it will be on a forged engine at 10 to 12 psi, so I thought that I would start with the 2 bar sd tune so as to not have to switch over later.

I don't have a superchips file for this car, but I do for my 01 vette which also has maggie, wi and 8 psi on a modified superchips tune.

What does the superchips tune do in the boosted areas.

All I could see is some extra PE ...doesn't sound like much of a tune.

Also on the original car in question, with the 90mm snout, oem Z06 maf becomes a bottleneck.

I am in Florida, so weather changes are not all that big or that often.

I went sd, because I also have a sport compact running sd tune with a Haltech ecu and I am very familiar with that ecu and sd side of things.

as for a boosted ve starting point check out the 2 bar demo in our help file www.hptuners.com/help as soundengineer put together a good starter example.

Can you point me to this?

I found the basic help file setup stuff for 2 bar, but it just states: make the boosted area richer...but how much richer?

I copy in my old VE table (up to 105 Kpa) and then put in 150 in the 210 Kpa row as a starter. Then do the poly blend from 210 to 105. Should be ball park.
