Id get with them and see what the map is for your set up. Its going to depend on a couple things but you'll prob. get told ~45-50#
Give HTT a call ask for Jonas or Dave, they will give you good advise on the subject, ive made great power from thier Pro Street 66 in the past, its been much higher than that boost wise and always held in there, thier a tough charger for sure, just watch the drive pressures, and keep them in check and you will be fine.
