iono, im running 9.0 comp pistons and my block is sleeved by RS..was checked for cracks and everything, but i am also running 5 pounds of boost...and my turbo kicks in quite early at like 2800 rpm's...i get a lot of low end power...i was thinking of jumping it to 8 or 9...im thinking that it is safe, but the problem is that my car is already eating gas like crazy...and i dont want to waste anymore gas...since im a college student with a 7.25 per hour job...i also think i am running rich...but i think imma go get me a 8 pound spring for my wastegate and then find a place to dyno it..and figure out of i am running rich...
