    Reflash vtech 1000 injectors

    Hi, Ive got a question. Im going to get a Reflash for my 08 Yamaha SHO from VTECH for the 1000cc injector 8600rpm. I going to fit a set of Riva 1000cc injectors that have and i was wondering is it really necessary to get a fuel pressure regulator or will it work with out it? Looking forward to hearing your responses, Thanks

    No RRFPR is needed with this setup.
    I'm running the V-Tech stage 4 tuning with 1000cc injectors on my turbo VXR and still running stock fuel pump/regulator.

    Hi Jerry
    Thanks for the information about the injectors. *I tested my FX SHO 2008 in Cadiz at sea on thursday. The sea was perfect for trying out top speed. **I tried my ski with the R3 reflash standard injectors and with the GPS the speed was 125km/h. **I then changed the ECU to the Vtech 1000cc @ 8600rpm *reflash with the 1000cc injectors fitted. *I tried the ski again with the GPS and only got up to 112km/h. *I dont have a fuel regulator fitted but i thought it was a massive difference in speed between one and the other. *Is it because i havent got a fuel regulator fitted?
    The specs of my ski are: R&D Comp air filter. Riva intercooler. C3 supercharger wheel. R3 reflash. *HKS blow off valve. Prop 13/23. Riva ride plate and intake grate. *R&D single *valve spring. Thanks for any advice.
