LS's come with 142 stock, they usually dyno around 120fwhp, i've got a thermal cat-back exhaust, AEM SRI, and my FPR is currently set to 40psi WOT. for the money i paid for the kit, it will be a nice little power gain.

 

Did you get 1 point colder burning plugs and retard your timing 2 points the plugs I use in my ls are ngk v-power zfr6f-11 and also when I spray i put 93 plus a 7 point octane booster in it higher the octane the better

 

plugs are on the way, and i'm going to have Sam at coastal do my timing and put it on the wideband.

 

100 shot on a bone stock motor????? what the hell are u thinking bro?!?!?!?!

 

i'm only running a 60 shot right now

 

do you plan on at least getting some valves, springs, and retainers before the big shot???? Ive seen what a 100 shot can do to a stock valvetrain..... It isn't purty....

 

yes, but i was lazy and didn't want to go into detail

 

gotcha

 

A b18b can handle a 75 shot all day long.
Retard ignition timing 2-4 deg & check your a/f using a wideband 02 on a dyno etc.

I highly recommend you purchase a new exhaust manifold to make more power....
Also pulling your power steering will help...
