OK. I have a 89 coupe with a red topsr20det, T-25 pushing 12psi, FMIC, Erything else stock.. The car runs good but brakes up in the high revs. Idles awesome and rides the gears awesome at about 80% acceleration. When I floor it the car feels like a pig. I have full boost but the car does not run through the gears as fast as it does with less gas. Any Ideas.? Does anyone know where all the vaccumns on a sr are?

Should I go back to stock psi?
 
plugs, fuel filter, vacuum/boost leak..

And there are no vacuums on your sr, unless it was a special "hoover" edition.
 
Your motor isn't getting enough fuel. You need to get an upgraded fuel pump. Walbro 255 is the most common and most reputable. Around $80.
 
and i did say go back to stock boost wich u can do it in 30sec i guess with a boost controller .. if problem goes away, then get a walbro fp and turn the boost up again.
