MS3 is a great choice, not much it can't do. I hate wiring which was one of my reasons for the plug and play version of the MS2. I'm sure I could have built my own and got it functioning, but didn't want the downtime or chance of screwing it up LOL! It's complicated, yet fairly straightforward at the same time...if that makes any sense. My biggest hurdle is getting a steady low idle speed, which may be the cam and the ancient idle air control motor I'm dealing with. Driveability is fantastic even with the batch fire fueling, no complaints there at all. Boost tuning has gone well, some street tuning and a few track visits got me pretty close, and I haven't really touched the timing tables yet. I'm pulling huge amounts under light boost.
Mega squirt has me very intrigued.
I will likely go that route next year.
For the time being would I be able to run the car essentially stock with the blower at low boost?

Here is my recipe lol.Sct 2600 mass air, sct chip, b-cam ,255lph fuel pump 44 # injectors ,tfs heads, gt 40 tubular intake on a 92 block ,10 pounds boost on a safe tune car made 483 hp 447 torque.
It’s the guest of honour at the dinner table

Does anyone know if there is a table to figure out boost from pulley size?

You can estimate any boost level with the following formula:
((Crank pulley diameter/blower pulley diameter*blower displacement/(engine displacement/2)*14.7) - 14.7)*Volumetric efficiency
Volumeteric efficiency is about 90% typically
Example: 5L motor with a 1.5L blower, 6.5" crank pulley and 2.62" (2 5/8) blower pulley
((6.5/2.62)*(1.5/2.5)*14.7-14.7)*0.9 = boost in psi
boost = 6.46 psi
same motor and pullies with a 2.2L blower:
((6.5/2.62)*(2.2/2.5)*14.7-14.7)*0.9 = boost in psi
boost = 15.65 psi.
Awesome. So with my current 2.5” blower pulley and my 6.75” crank pulley I would be making roughly 18lbs Of boost. :s I think I’ll be buying an underdrive crank pulley
