I replaced all my vacuum lines on my 86GN, and she seems to be really idling smooth. I took her out and stood on it, and she spooled up quicker than she ever has before. No laziness there. However, I don't have a tach and the rev limiter on the chip is set at 6000. The RPM's came up and the motor started breaking up and chugging so I backed out of it. Boost was at max (15psi). It felt like I hit the rev limiter, or it felt like I lost an intercooler hose, or something similiar.
I tried to get back in it again but it was now chugging at a lower rpm, with a hestitation. Driving down the highway if I got into the throttle even part way I would get the chugging hesitation right away.
I limped it home and the hoses are all on. Any suggestions on what was going on here?
