whatever, the AP2 has a nice kick, right at 6500

I prefer a twin turbo kick at 3800, however...alot more fun
My ap1 kicks in pretty nice at 4500rpms when it has finally spooled up.

You would have to take the vave cover off to check the pins. You could also take it to the dealer and have them hook up the air compressor to it to see if all of the pins are engaging.

Well I have no check engine lights on. I just changed the oil and it seems to pull a tiny bit better, but overall not much difference.

I guess I will be taking it to the dealer. Do I tell a the dealer to test the pins that engage the high rpm cam's?

^^ The car had just had it's head off after an over rev. And we noticed the issue on a test drive after getting it all back together. I can only guess that some contamination got in and jammed the pin. The fix was to pull the rocker assembly off and work the pin until it was moving freely again.

Wow, then I would think there is little change this would happen if the engine was never dissambled or modified, correct?
