    What should I get?

    I am running a 100 dry shot. I am looking to upgrade injectors and fuel pump, but am not sure what brand is best for each. 42# injectors are what i have been told to get, i just want some feedback on a brand for them, and for a good fuel pump. Thanks.

    subscribing, the walbro 255 seems popular but i know from my 5.0 mustang days that those fuel pumps can be unreliable and i dont want to be changing fuel pumps all the time...

    Should be plenty for a big dry shot.

    there must be someone here who tunes ls1 and sprayed their car before and after headers, could you run more timing with the headers? how much more?

    thanks!

    Run a scanner and set it so you dont get an KR. No one can tell you specifically what to run. I can get about 21* out of my '02 (no headers) before I get any KR on spray... safe to stick in the <=20* range.

    perfect man, thanks! if you get headers would you mind updating me and letting me know if you can run more timing? seems like the headers should help the safety margin somewhat, i'm just not sure how much that is and if its worth it or not, i'm definately leaning to just spray it though, and i plan on having it tuned on the dyno professionally so should be about as safe as can be

    you had any issues with the stock rear end yet at that power level? i'm sure the torque is probably unreal compared to stock...

    LOL, the TQ is definitely there! Check my sig. Bottle ended up being nearly empty... but you'll get the idea.

    So far no issues with the rear end other than the classic whine that was there since the day I bought it. But I spray from 3000RPM in 1st - not straight out of the hole - so there is a little less shock on the car. My biggest complaint is my tires! Without a drag radial - you'll have next to no chance of putting all the power to the pavement!
