How does programming changes actually give car more HP?
I know this is kind of a newbie question.....but I have been wondering how programming changes (e.g. Powerloader, LS1Edit, Steve Wright, etc.) actuallt works to add HP to your car.
What exactly gets changed to accomplish this?
Any insight is much appreciated :cheers:

You can get more power by changing the air/fuel ratio. Leaning the car out gives you more hp, but overdoing it leads to possible engine damage. Also, you can change shift points in a auto, and or raise the redline limitter which allows you to go faster through all the gears :cheers:

Just Dyno'd my 99 I produced 293 RWHP and 303 RWTQ, several other C5's (two were stock autos) had well over 300, a few hit the 31X mark. The tech looking at my a/r ratios from my run said I left about 15 HP on the floor. When I asked what he meant he showed me my a/f ratios. From 5200 to 6100 RPM mine fell to 10.9:1 ideal is about 12.5:1 to 13.0:1
The cars producing over 300+ RWHP/RWTQ were closer to ideal then mine. My next MOD will be to have the car "TUNED" before I waste any more $$$ on mods. BTW this is what I have on my car when dyno'd:
MN6
Corsa Indy's
02 LS6 Lid
K&N Air Filter
14,200 miles
Two of the automatics one with a stock exhaust had better numbers but better a/f rations. I have over $1000 in mods so you can see my concern.
I think this is one of the first mods you should do before spending $$$ on all those aftermarket components that the engine might not like.
There's HP to be LOST or FOUND with TUNING.
