93 greddy kit not building boost, or am I?
The rundown
93 miata 1.6
megasquirt diy pnp v2
cx racing intercooler
genuine greddy bov
Greddy turbo kit
glowshift boost gauge
Here is my dilemma
the car starts and runs fine, idles good. When i rev it up I can hear the turbo spooling. Without the charge piping on I can feel the turbo push my hand away from the discharge.
when I connect the intercooler piping I register no boost on the gauge but can still hear the turbo and megasquirt reads 110kpa On the map. I'm building 20 inhg of vacuum at idle and it'll shoot up to 0 when revved.
I've checked the piping and there are no leaks, the bov never let's off any pressure, the waste gate never kicks open. BUT the first couple attempts I did blow off some loose couplers and blew off the IAC hose a couple times.
What am I doing wrong? Someone help me because I'm stumped.
Additional info that may be relevant.
I'm running the msq file for 460 injectors but changed all the values to match my 240s
I'm running a open downpipe for the time being
waste gate moves by hand and is free
car is in a non driving state so it cannot be driven

I should've noted it takes some force. Its not impossible but I wouldn't wanna do it 20 times in a row.
I did take it for a rip around the block yesterday, it scoots but I'm still only seeing like 2.5 lbs of boost. Should that small amount of boost make a difference?
I didn't have my laptop in the car so I'm not sure what the map sensor saw.
The whole reason I was confused is because 2 of my buddies have dsms and they build boost in neutral and a friends civic does the same.
Thanks again.

As to your DSM friends, this is all I can say.

If it was an aftermarket boost gauge, do they have automatic transmissions or aftermarket launch control? Either one allows you to build boost without driving (auto does have to be in gear with brakes on).
