I'm having boost creep issues on my h/c/i 302 with a B&G hotside with a MPT70 turbo and a 38mm tial w/g. I have a .6 bar spring in the w/g and it should only be making 9lbs. It makes 9lbs. in first and second gear, but in third gear it starts making 14-16 lbs. I know other guys running the same combo with the same w/g and there having no problems at all. I know I don't have a back pressure problem because I just have the downpipe dumping by the front tire. I need to resolve this because it's driving me crazy. I'm getting ready to buy a s-trim...lol

I had a solid 9lbs when I installed my kit - removed the mufflers and tailpipes and the boost went up to 12lbs now.
