Thanks for the input guys. Sounds like these numbers are a little more respectable than I originally thought.

 

I am scared to think what my numbers would be if I ran my truck at the track. I got a few mods: chip, K and N intake, Flowmaster exhaust and E fans but mine is a Screw so it its heavy. :o

 

SCREWEDUPF150.... never hurts to run it and see!


I'm gonna go again in a few weeks. Hopefully will get some cooler weather and some more time to get used to the truck. Also want to run it without the tune...... just to see what they did when stock.

 

I'd guess in the 17s. lol My 00' Scab w/ the 4.6l ran 17.2 with just a chip. Then I started playing around with it more

 

Should be way better than 17's........I have Xcal, AirAid, Magnaflow and I run 10.2's which is like 15.8~15.9 1/4 mile

 

Probably right. He's got a Screw he said but you have a Scab but 4x4 so I'm not sure which truck is heavier. Will depend on what gears he has and what engine he has since he didn't mention that.

Man, I don't even know what these new trucks can do then. Wonder what mine runs now...

Take it to the track and let us know! Only problem I have with changing tunes at the track (changing back to stock) is the truck's computer would have no time to "relearn" before the next run.

 

One thing to remember is altitude and weather make big difference. I have run my FX4 two different times here. First time adjusted altitude was ~4500ft with best et 17.15 with the Superchips still in 91 tow mode. Ran it Friday still in tow, but with the AF-1 installed. Adjusted altitude was ~ 6600ft and it ran a best of 16.85.

Next time the race car is broken, I will try the 91 performance. Someday I would like to hit a track close to sea level...........
