FYI: I am installing the coil pack on Saturday when i finish up my spring swap, so my 1st fill up with the new coil pack will be then.

I kept my record of my last 4 fill-ups with my truck (keep in mind that this is over a period of about 1.5 months since i dont drive my truck on a regular basis). 99% of the driving was done in the city (since i drive my truck on fire runs i can not say that this is easy driving, but not pedal to the metal driving either)

Stock Coil Pack (most current fill up is listed 1st):
-14.6 mpg city
-14.4 mpg city
-14.9 mpg city
-15.2 mpg city

After Coil Pack:

UPDATE (1-21-07):
Screamin' Demon with stock gap:
-11.75 mpg city


GAPPED THE PLUGS OUT TO 0.065"!!! (1-23-2007)
Truck runs A LOT smoother. Idles 100x better than any configuration before. Revs 100x faster also.....Just for those 2 improvements the $80 was worth it....

**FILLED UP YESTERDAY (2/6/2007)**

Screamin' Demon w/ .065" Gap
- 16.2 mpg (mix city/highway milage)

SEAT OF THE PANTS RESULTS AFTER GAP:
-better acceleration
-better throttle response
-faster pickup

Filled up Saturday 2-10-07 (this was with the Bama and the Screamin' Demon...)
-15.9 mpg (city) with not an easy foot.....

2-20-2007 (again with Bama and Screamin' Demon ALL city driving not being easy with the right foot!)
- 13.8 mpg (city) with not a easy foot

WILL ADD INFORMATION IN HERE AS IT COMES IN! EACH FILL UP I WILL UPDATE THE POST!!

**UPDATE** (3-21-2007)
I filled up last Saturday, March 17, 2007.....i got 15.5 mpg on that tank.....that was strictly city driving also.....


Here is pictures of the Screamin' Demon coil pack. It looks just like our stock coil pack, but you know what they say, "looks can be deciving!"

NEW PICTURE ADDED!!!!! it is an installed picture....

i really like this thing....my truck runs smoother with the plugs at stock gap and it idles smoother also at stock gap....throttle response at the new gap is better......faster pickup also...
