yep too much pressure. Stock is in the 39-40 psi range, and with your mods it will most likely run better leaned out a bit. I would try dropping it down to around 38 and see how it runs. I'm assuming your heads are stock, so the 24's are alot for it anyway, but 45 psi with vacum off is way too much.
