I haven't deployed any Rocket PtP links with less than 55 signal.
Have you followed UBNT's best practices guide?
http://www.ubnt.com/downloads/Best%20Practices.pdf
Next step, hit up their forum or their support. Matt at UBNT worked some
magic on one of my links and it has been solid ever since.

Ok tried 20mhz, throughput drops about 10mbps to about 30mbps. My
signal is at least 20db better than noise (signal -59 noise -85+).
ACK is set auto with distance of 2 miles (actual distance is approx
1.5mi). cable not an issue. any thoughts?

You probably either have 1) noisy channels, 2) incorrect ACK
distances, 3) not optimal firmware version, 4) Or some third party
factor effecting testing, such as testing devices that cant generate
that much traffic or buffer sizes of routers.
The first thing to try is switch down to 20mhz channel and see if the
speed tests stays the same or higher, or if it drops proportionally. I
bet the 20Mhz channel will perform better.
Dont rely on CCQ on its own. Its one indicator, but does not mean you
have a clean channel for sure. Also remember, the Eth port is limited
to 100mb, and if there is cable quality issues such as due to
distance, it could autoadjust to half duplex. Test laptop to PC,
isolating RF path, just for grins. It is very rare to find 40Mhz of
clean spectrum for Dual polarity, and even the slightest packet loss
and delay can drastically reduce TCP throughput.

Problem is when I turn airmax on the speed really goes in the
toilet. Best I can get is about 20mbps. According to ubiquiti
airmax needs to be off up to 15km links, anything over that
airmax needs to be on. Do you have good success with short airmax
ptp links?

Turn AirMax on.

What is the best real TCP throughput up/down anyone is getting on
a PtP ubnt connection? We have two rocket M5 approx 1.5 mi, CCQ
97-98%, 40mhz channel width, airmax off.
Displayed TX/RX rate is 270/270. Real TCP throughput via iperf
radio to radio is 40-45mbps.
Are there some config changes needed perhaps?
