Thank you, I was wondering if those people claiming they have massive tire spin are actually driving an 04-06 NA F150s, mainly scabs or screws. All this talk of "power down low" makes me also question this because I usually get beat off the line, mine is a slug off the line even after reflash and 3.73s. Im just making sure we are all on the same page here.

On the 5.4 3V, I am not too pleased, mine makes a bad rattle tick at warm idle, vibrates at idle, and Im not looking forward to the spark plug change approaching. Oh thats right, the spark plugs are supposed to last 100k miles.

 

I haven't seen any claims of massive tire spin, but tire spin does happen. Watch this vid and listen at the launch. This is only slight tire spin, but I have the 3.55ls rear and I'm running 32" tires. Without the ls and with lower gearing and/or smaller tires, serious wheelspin would be possible.

 

I've spun my tires in reverse going up my driveway!

 

I have a 04 2wd screw with 3.55 in the rear.It was easy to spin the stock 17 " tires that came on the truck .I put some pirrelli 275/55 -20 0n now and gues what ,I can still spin them very easily .Power for my truck has never been a big deal but i probally will order an edge to correct the speedo ,firm up the tranny and get rid of that throttle lag.

 

8.2 0-60 and 16.4 quarter? Are you lifted running biger tires? Any other mods? I have 35"s with 6" lift and my Edge tuner is on level #2 running 87 octane and I 'm getting 8.0 0-60 and 15.7 quarter time. Just curious.

 

I'de kill myself if I got beat by a stock denali

 

I have a catback magnaflow, thats it....just out of curiousity, have you changed your tire size to the right size??? What elevation are you at?? Shift points?? Maybe I just need to do some fine tuning, awesome times by the way.

 

Its not that important to me
