Default 460whp on stock LS2 injectors....

I am guessing this is not really possible. New parts and a new tune brought me to 460whp. Caveat is I live in Denver so the correction factor on the dyno sheet reads 1.25. So actual whp is alot less. Maybe someone can tell me what actual is from the correction factor.

My problem is I am heading to San Diego where the car is going to put down 460 and I don't have the injector to support that I am guessing. If I keep my foot out of it should I be ok?

I know I should be checking with my tuner but this interview just happened and I got to get.

At your elevation you should be fine. At sea level your probably going to hit 100% duty cycle. It will be ok if your not holding WOT.

I was running about 500 flywheel HP on LS2 injectors and saw 96% DC.

i saw 110 percent idc on my cam and intake ls2.

hit 90 percent in the summer once the tune was dialed in, when fall came around the injectors were useless, started going lean up top and seeing counts of knock retard.

always give your self a nice 15 to 20 percent of space till 100 percent on injectors.
you dont want the injectors running static, bad for your motor and pcm.

Thanks for the info guys. I am going to just light foot it while in California and when I come back install some 46# injectors. Is adjusting the tune for these like a full tune or should I try and get a discount on it. Current tune is only two months old.

Damn 500/450- I wish I had those numbers. MS3, PAC 1521's, Flowtech 243's, FAST 102, SW LT's and Vararam and all the setup could muster was 460/419. I need a tuner and guidance from guys like you! I know some of that was my choice to stay with CNC'd 243's.
