    Is there a write up on what to do on the fuel rail? Some people say a ssic isn't worth doing what do you think? Do you think it's worth changing my valve springs to 105's and leave the single roller?

    I love how people waste so much money on **** they don't need. 105s, a new stock timing set, new valve seals and retainers call it a day.

    plenty of dyno pulls that show the difference between a 90, 105, and a 130 lb valve spring. do you need a 130? no, I have an XP and am running a 90 lb LS6 spring, but the 130 will support a steady increase in power at higher rpms more effectively than the 90 and 105.

    Okay, is it enough that you will even notice a difference? Or are we talking about 0.01 of a second off the in quarter.

    I'll let you after I change springs, the dyno sheets I saw with the 90/105 springs started losing power after 4500 rpm, the higher lb spring maintained and our gained a little

    Yea I'd like to see exactly how much is gained also I mean if it's very minimal I don't think it would worth the valvetrain stress for a everyday summer car do you guys?

    What fuel pump are you guys running that will support 42.5 injectors or bigger for everyday driving? When I put in the 42.5 injectors can I still use stock fpr?

    its not that you get more hp, its that the torque curve doesn't dip after peak hp is made.

    South Florida ain't nothing, try Houston Texas. 160 is too low you will always be in open loop wasting tons of fuel. I haven't seen anyone tune for a 160* thermostat.
