I bought mine from Summit Racing online. It was a MSD 3 bar for about $55 ;D

i can get a 2.5 from a sun bird turbo and i might go pick it up on like thirsday or friday

Re: Gm 3 bar Question?
 

Please just don't a 2.5bar is the same as the next.

Different Map Sensor output different voltages at different manifold pressures.

The Digikey Motoralla Map works. Find the manufactures web site to get the voltages vs. pressures, the you have to find the GM 2.5bars voltage vs. pressures. If they don't match, there probably wont be a .bin for you to tart with.

ALSO: There is no 2.5bar Sunbird MAP sensor. It's a 2bar which is basically no upgrade from a stock honda.
