I really like the Isspro's too. I was in touch with Michael at Isspro before they had the gauges for the OBS trucks but he told me they were working on them. Michael was up front with me and said it might be a while before they were available. I waited for about a year for them to release the gauges and I'm glad I waited. :thumb: I just didn't like the looks of the Autometer and didn't want a mechanical boost gauge either. Maybe I'm just too fussy.
