I ran performancebox on my 98 c43(0-60, 0-100...)
So we ran this tonight and here are the results
First id like to point out that im losing around 40 hp due to bad plugs and wires. 117k miles on same wires and plugs. The car is putting out around 250-260 at the crank at the moment
0-60 in 5.8 we only did two runs
0-100 in 14.4
30-100 in 12.1
100-140 in 18.4
1\4 mile in 14.3 at 99.72
in 1 mile distance, the car got up to 143 mph
keep in mind this is a stock c43 losing around 40hp
here is the list where u can compare it to some other cars

and here are the mph\distance graphs

Did you dyno the car recently? How do you know its off 40hp at the crank? If that # is right you might need more than wires.
When I first picked up my car it was running rough on the dyno due to MAF, plugs, and wires. It didn't lose 40hp though, seems like alot.

If you truly had bad plugs and wires you would have seen a misfire under load.
Numbers you post are typical for a stock C43.
Change the plugs and wires and you see a slight improvement.
Your "crank" number should read as RWP which based on published crank would be about correct inclusive of drive train loss.

you can also dyno your car with this and my car got 257 at the crank but we only did one run
I scaned my car and I got a bunch of misfire codes a few weeks ago. Its also noticeably slower when I drive it. When I punch it, it just doesn't have that same kickback it used to have

Are you positive the number you get is at the crank ?
Typically devices like these read RWP not crank.
257 RWP is in line with the published 302 HP at the crank.
This would give about an 18% +/- drive train loss, typical of the results you would see on an inertia dyno.
Plugs and wires should clear the misfire problem, but don't look for +40RWP !!

Doubtful....
Pulstar plugs really will not give any additional horsepower beyond a typical dyno tolerance.
Corvette Forum rana few independent dyno tests on plugs supplied directly from Pulstar.
They were installed in several stock 05-06 Corvette LS2 engines with no appreciable power increase.
