    Throw the B-Kit in there now with the Riva ECU and 50's and you will be in the 80's. With out the B-Kit you not gonna see much gain because your not adding any HP.

    If you go with an ECU your gonna want to get some sort of Valve spring/retainer upgrade done..Either Rivas or Les Cookes....You dont want to be dropping valves...

    how many hours on stock valve springs? gonna need to upgrade at least the retainers! if the green wheel keeps building boost, you'll see more power at a higher rpm.

    Many people have run 75 - 77 with your current setup, added Riva ECU, 50s, and valvespring upgrade and ran 80+. You will need to pull back your 15/20 trailing edge 1 - 2 mm to get your rpms up to 8500, but once you do that, if everything else is set correctly, you should be able to hit 80 mph. The GW is enough to get you to 80 if you have a Riva ECU and get everything fine tuned.
