i just did a redtop in my s13 and i havent put in a walbro 255, i want to bump the boost up but i dont want to run it lean so i was wondering how many pounds of boost i can run befor running it lean?

Why not just wait until you put the 255 in??? Its only what... like a $90 part and takes 30min to put in max.. just leave it at .8 so you dont risk wielding your pistons to the cylinder walls then having have to ripp it back out and spend more money another block
