Something isn't right. Either you had an awful launch or your truck isn't running correctly

Can you post all the time slip info?

10ft: .79
20ft: 1.86
30ft: 3.06
40ft: 4.63
50ft: 6.66
60ft: 8.81
70ft:10.99

On the time slips its usually something like:

Reaction time
60ft
1/8 mile time
1/8 mile speed
1/4 mile time
1/4 mile speed

R/T.............898
60'...........2.233
330..........6.474
1/8.........10.028
MPH........69.54
1000.......13.086
1/4.........15.714
MPH........85.21

Track elevation 190 feet
September, low humidity

1999 F150 2wd, reg cab, short bed, 5.4L 2valve
265/16/70 Michelin
empty weight 3900 lbs
Stock, no modifications

Time/speed will be slower at higher elevations.
Also high temps/humidity will factor.
Mid July slowed my truck by over a half sec.
That was many years ago.

The only 17.49 truck I've seen at the track was when I talked my brother-in-law into running his stock mid-ninities Dakota 4x4, six banger.
He ran 17 and a half all day long.
