Its a Canadian Vancouver police bike , ive sent a request for service / specs to them and they have responded that they will dig up what they can for me . Any other way of finding out this info ???

Nice, They probably had Deeley do the service and Deeley may have to build records as well.
I'd head down to deeley with a box of timmys and see if they'll help you.
you can decode the VIN using a service manual too.
My evo cop bike is a CHP bike and fast...but the Cal. regs exempt State owned vehicles from emissions regs ( which explains the school buses sending out soot by the cubic ton.
CDN regs may have determined a truly stock version of the bike.
stock evo is 55 hp ( 45 in Cal.), my FXRP was 64 hp when I bought it ( I think you'd feel that 10 hp)
2/1 pipes, high flow intake and a swap from the kiehin butterfly to the CV carb went to about 75 HP.
visually it is hard to tell heads were milled about 0.060" which is hard to see , but can be down side by each with a stock evo.
cam, the easiest way to tell is to open it
as for the original tuner question...I know nothing. I stay so far away from M&M EFI I won;t even park next to one.
some of the guys have had good ( or ok results considering that the M&M offered less power, MPG and higher emissions than the carb version)
check in at the evo forum- those guys are smart

You can go with a Power Commander PC III USB from Dynojet for the MM efi. Load their suggested map & tweak from there.
I had one on my 97 RK but could not get rid if the decel pop altogether.
I'm switching to carb this winter along with EV27 cam in hopes of waking up my Evo.

I built my '98 Ultra with Weisco 10:1 pistons, an EV 3030 cam, and flowed heads and used a simple power commander to adjust the EFI. It worked very nicely (I even got rid of the Decel popping too.)
