Sounds plausible to me..... engines less efficient (valves not open as long) so boost pressure goes up.

I'll double check it's activating tonight with the N1200 attached (I know its getting the signal as the AEM has logged it).

Cheers

 

are sure you have vtec almost sounds like your on the small cam that would give you bookoo boost and timing would be way low due to the high compression with the high cam dynamic compression is around 9.1 but low cam is 11.1 so that would explain the boost and low power i am in process of installing my new 1200 with a 6.75 crank pulley and a 4'' charger pulley and i expect 12-16psi current novi 1000 is 3.8'' blower pulley and i get 12-13psi at 8300rpm 14 at 8500 so i would be looking to get a second opinion you might get evans to look at your tune or if anyone on here will take a look and see if something doesn't look right

 

I agree. All arrows currently pointing to running on just the primary cam.

I don’t understand why there is this issues when swapping blowers. When I did my NV1000 to NV1200 conversion I had to also swap the vtec oil feed line and nipple to the NV1200 if I recall. I used the same top location as the NV1000. As long as you do this, there shouldn’t be any issues.
