Hey all, my rb20 poped a cooler pipe on a spireted run, so I fixed it up and now im noticing a boost differenc from gear to gear of between 1/2 to a full bar. That just seems to be a bit much. Its stock except int/exh, ball and spring mbc (set to 8 bar, witch was consistant in all gears before the pipe) any info will be appreciated. Cheers.
