just wondering if any one has seen this before, I've got a 3rd gen with the stock sequential setup with the pettit ecu and the greddy profec b spec 2 and I'm getting a really slow spool/response in the low end, it barely hits 10psi up to about 4k rpm and after that it jumps to the set 15psi and hauls ***. I've gone over my settings on the profec and its the same as it was before the problem, it has 18" of vacuum at idle so I don't think I have a leak. I appreciate any ideas or suggestions, thanks.
