You shouldn't have to travel around, getting a tune for you to begin with will be easy.
The tune I sent Denmah(Matt), to start with, will work for the third gen engines(LS1,L33,truck engines(24 tooth engines),etc.)
Plus, I have start up calibrations for the gen iv engines(58 tooth) also, These engines won't be a problem at all with the Microsquirt,or MS3pro.
The older MS3x stuff ,and the aluminum cased stuff is a little more difficult to get setup,and triggering, but with those guys around you, it can be "do"able.
If you need any input, email,or PM me.
I am worrking on a GN LSx conversion myself(street car with air,power steering,4l80e,and an 88mm turbo), a tube chassis 3rd gen Camaro twin turbo(same set-up as my Nova Wagon), and a 67 nova conversion to name a few.
There is also acouple of really cool devices out,and coming out.
One is like the Scanmaster, but it is in a round guage format,and reads CANbus signals from the MS2/Microsquirt/MS3
The other is out already and it is a CANbus expansion device, that will read the Innovate serial stream for 8 O2 sensors and send it to the squirt VIA the Canbus, It will also read 8 EGTs and send them to the Megasquirt variants with the Canbus built into them.
and at 299.oo it is not real expensive.
