    Lightbulb Injector advice

    Hey all.

    I have a 08 rxp-x 255 with a Riva ecu 8650, stock X wheel with all supporting mods. I am currently running a cmd with autotune. I am about to purchase a set of injectors. I'm looking for some input on either 60lb Siemens/deka or 80lb to use. I would like to have a little more room to grow (et137 or 68-140 and maybe more rpms). I read that the 60lb has a wider spray angle and multi hole head. 80s have 1 hole and narrower spray pattern. Thanks guys!

    IF your running the CMD with auto tune,Then i would go with these 80s....Use the CMD/autotune to get your AFRs were you want them...THEN if you decide to upgrade,you will already have enough fueling to cover the upgrades without having to keep buying bigger injectors all the time...

    +1 on the CMD best thing ever. Easy to use and dial in. And you can swap chargers and still have the right fueling if you set it up as MAP vs rpm. Really cool stuff
