Im just going to go with a fuel pump, injectors, and a tune. Much better than any other piggy back system. If you dyno tune it also you probly will make the most horsepower anyways.
yeah im thinking i might actually get a madz28 pcm from him. He made it sound like he could make my car work without much effort. And right now i cant afford a dyno tune in my area. The only one close to me that could do that is Hardcore racing and they are over 500.00
i used a cobalt ss 2 bar map for my setup, its good to about 15psi and 800+rwhp. Im moving to a 3 bar this winter. I believe you can use sensor from a turbo ta or grand national.

All you have to do to go "SD" in a lt1 is unplug the MAF... but like i said in a ealier post... "Speed Density(stock pcm), boost, and LT1 do not belong in the same sentance". Simple fact. It is nothing like a LS1 computer

Again... this is not a LS1. You cannot use a multiple bar MAP sensor with the LT1 very easily as far as I have seen. Someone was trying on camaroz28.com but they are having little luck.
It may be possible but not worth it. Add fuel for boost through the PE table.
If someone wants CHEAP SD capable of taking boost on a LT1 then megasquirt (couple hundred bucks) is the answer. Then comes the problem of the OPTI with that. But people have found easy ways around it.
