Losing boost on the shift

[TWISTER]

I took the buick out tonite and noticed the boost would drop off on the shift. On alky it went from 21 down to 16 then back to 21 till the next shift. I have a heavy duty actuator and not using the solonoid w/ a grainger type valve for boost control. It was very hot and humid but thats not going to contribute to it. Never had this happen before. Thought Id ask before I went searching. TIA

you may be....

pushing to much alky. it's cooling the charge too much. reduce the flow or bring it on at a later boost. Ambient temp/humidity will affect the volume needed. Hope this helps.

Ahh that makes sense. I didnt have any knock at all and it was way to hot to take the car out no wonder this hasnt been a problem. I need to turn it up anyway. Thanks
