Hey guys,
Looking for some advice here...
2018 Mustang GT w/ a stage 1 Procharger HO kit. My stock pulley was a 4.38" and it was rated for 6.5lbs ( I constantly saw 6.2 lbs). I've since changed to a 4.10" pulley and was told by Procharger that I should make 9 PSI with this. Since installing the new pulley the max I've seen is 7.6 lbs. My question is, should I be seeing more boost or is 7.6lbs correct for a 4.10" pulley?
Thanks in advance!

- I'm reading boost through a mechanical gauge
- The belt is tight/ no slipping
- PBD tuned- Shoemaker says he expected to see more boost
- The power from the stock pulley to the new one isn't really noticeable ( maybe a boost leak somewhere?)
Thanks in advance!
