    well judging by your sig you are off to a good start :

    riva ecu,valve upgrade,50lbs,rrfpr,riva thru hull exhaust,riva wedge,riva 3inch air, catch can [email protected] grate,girdle,pumpshoe,xs cooler, speedfreaks bracket,and short pipes,RUDE1 CHARGER,R,E,blockoffs,riva nozell,81 ring,groco strainer,pitched up 15/22r....next mods AFR KIT AND FILL RIDE PLATE,GRATE ECT,CUSTOM METAL LINER,+PROPS TO GO

    perhaps it would be best to narrow it down to what your options are at this point and realise that it all comes down to money. You set yourself a budget, or like some guys here DONT, and go from there. And if it just TUNE at this point, plan on a change to the ECU, I know you said you didnt want to but fuel management and delivery is very important and requires some finesse. Most of the go fast guys have figured this part out, it is a chunk of change but a big pay off as well. Plus, use the search function for specific questions that you might have, chances are good someone else has asked them before ...

    Change out your super charger wheel and housing for riva or ET 137 upgrade.
    I think will need 50,s injectors for that also according to riva.

    Relocate your intercooler. Make your own bracket and plumbing if on budget.

    Remove flame restrictor in mani.

    New prop and pro nozzle if looking for top end.

    Go thru hull exhaust pipe with stock water box.

    I have run 75+ in cool condtions with all mods except the SC mod and injectors.
    I will run 73+ in summer heat.
    I think with sc upgrade and injectors you can see 75+ in heat.

    IF I DID GO ECU,WOULD IT BE BETTER TO BUY A NEW UNIT,SAY RIVA OR ROTAX,OR WOULD SENDING THE ORIGANAL TO LES COOK BE AN OPTION,IM AWARE THAT THE RIVA KEEPS THE WARNING CODES ALIVE ON 07s,not sure what does what on the 08s
