I just finished installing a Isspro Mech fpg today, something I haven't found mentioned is how quickly do these gages respond ?
I'm off the VP test port with an adaptor from Ginos, hooked to 1/4 braided stainless with a needle valve in between (open 1 turn)
At startup/idle it took a couple of minutes to reach 13psi, that appears to be max, I tried WOT, but I hit triple digits (for the first and only time!!) still accellerating with no end in sight, it pulled down to 9psi, but real slow, my shield of invincibility isn't as thick as it used to be and I ran out of straight road so I had to slow down.
Do these things all respond like molasis or do I have a problem ?
Thanks for any input.
