    rxp injectors question

    i have a 07 rxp with et 127, 4 inch intake, 160* thermostat and 42lb injectors. im planing to add an ex ic in a few days and a lot of people say i need a rrfpr with this set up. i do not have a afr to fine tune it, can i just add 46lb injectors and be good. i know 48lb will be too much. im in south florida so only ride on 80+ degree weather. if anyone has any idea on the topic plz reply

    this is not the way to get help here

    skidoochris is telling you your best bet, you decide what to do

    Just for the record I will tell you that I transfered all the mods from my old RXP to my new RXP and the fuel tune was way off

    good luck

    ok I will guess for you.... the 42 lbs will be fine I bet you will be in the 12s
    you don't need a gage...if it blows up you were too lean ....simple

    DUDE....you don't get it no 2 skis are the same!

    Without AFR gauge its just a wild guess, regardless of who answers your question.

    The thing is that i dont need an obvious answer that i know DUDE..... the afr gage is the best thing to do, I KNOW, but that was not the question. Thank you for your help but all i want was a simple yes, no or it better 46 even if u r little rich. I dont try to be rude but lets stick with the question plz

    46/48s will be to much for this setup...You need to stick with 42s AND a RRFPR..NOW the key question is what are you going to set your pressure to????And how are you going to know how to set it to that???As everybody has stated you ARE going to need a RRFPR or a CMD and an AFR gauge wether you like it or not....Bottom line...These guys are not "Giving you attitude" BUT trying to help..These guys have been around the block and know what is up..Yes they seem like they were being stern BUT it seems like that is the only way to get through to some people..Obviously you didnt want to hear about the CMD, RRFPR or the AFR gauge,BUT rather wether or not you can just slop a set of injectors in and go...So being that was your original question,Then your answer is NO..BUT if you chose to do so anyway it is at your own risk...You have been given the information needed to point you in the right direction to start with..

    Thanks and have anice day..
