    You could have a chat to Mace Engineering about getting a tune close to what you need. But as mentioned above it really needs to go on the dyno.

    What are you after? As said going to a dyno is your best bet (ace performance tuning etc)
    Or are you after a reasonable base tune memcal so you can drive to the tuner (delcowizzid should be able to help)
    Or are you keen to tune yourself with wideband, data logger etc (most of what you need can be had from delcohacking.com)
    Or lastly there are aftermarket ecu's that might be easier for you (haltec / link)

    P. S interested to hear more as my combo may be similar to yours

    Best choice is throwing a ECU in (haltec seemed to have forgotten their roots and wont do a plug and play 750) or just be a man and go carby with a 750 street demon and torque power intake.

    Did you do the stroker? Did you add a cam? Did you leave the ports stock? If yes on the latterest you should've had a bowl job done on the heads.

    Nope Memcal is shite. Any upgraded engine needs to be tuned on a dyno. You can dissagree i don't mind but I know I'm right.

    Nothing wrong with a memcal.
    You can still dyno tune them.

    "be a man and go carby"
    Really? What a dumb thing to say.

    Didn't think fitting a carb would be street legal on a VN?

    Exactly.
    And to suggest all of the extra expense of mani/carb/reg etc when what he has will do a great job of what is required.

    Yes but Shane is right and he doesn't care what anyone else thinks.

    Personally I think he might have been smoking some green stuff with his beers last night as even i know a VN with memcal can be dyno tuned, and I'm not a mechanics arsehole.....

    As with anything in life, you get what you pay for. Getting a cheap memcal from ebay hasn't ended well for more than one person.

    Thankfully no one so far has suggested an eBay memcal. Although every now and then a new member doesn't like the idea of spending $180 on a decent mail order tune and especially not a custom tune for 7x that. Hopefully the OP is not looking for a cheap tune, considering the effort he has put into the engine.

    If you have all the specs of engine + parts & they're actually accurate then couple of recommended tuners should be able to get it to run decent enough to start/drive BUT don't expect it to be perfect as description posted sounds like it will probably need dyno/road tune.

    Most mail order tunes work well for stockers with limited or common mods that have been done to death repeatedly.

    I was thinking of some thing along the lines of a base tune, I also have a haltech interceptor for it as well, it also needs to be wired to the loom

    So mail order so you can run it in and drive to a performance shop. Then the performance shop wire in the haltec and dyno tune.
    Sounds like a plan.
    I've got no idea where you are from and what your nearest shop is though.

    Yeap, that's all.
    It wasn't finished at that point.
    Going again in September to see what gains have been made over 3years. Hopefully low 13's. It went mid 14s as a 304 with stock cam.
