Sudden boost drop on JRSC
Last week my car was dyno tuned and constantly hitting 7-8psi. Yesterday I couldn't get it to go past 5psi. Seems like it hits a limit at 4.9psi and just drops hard below 1psi.
I checked the belt for slippage and also checked for vac leaks, but everything seems normal. I'll probably look for a better leak detection method, but besides that, what are the other possible causes for this?
B18C, JRSC with 3.8 nose pulley & LS crank pulley.
