yeah well i cant spin my tires either when its dry. im kinda mad about that. does anybody know what the power difference is between my 2valve and the 04+ 3valves, and then each with a custom tuner?

 

Justin has some dyno's up on the VMP Tuning website forum.

Here's what he says about the truck he dyno'd in this tune:

Jason wanted to wake up his 05 F150 5.4L 3v so I had him install exhaust, intake, and then he brought it to me for an SCT X2 and Dynotune. This truck still had stock tires and stock 3.73 gears.

Here's the dyno:


Looks like it went from 210 hp to 240 hp if I'm reading it correctly.

Not sure what the hp is on a 2 valve, but this answers half of your question.

 

thanks bud. wonder what a race between a 2v and a 3v same tune same gears etc... would be like

 

I ordered my SCT X3 from Justin and I am very happy with it so far! I got the performance, tow, and mileage all in 87 octane and I have yet to try the tow and mileage tunes. Plus I got my X3 in the mail with the tunes loaded on it in about a week and a half! And Im on the other side of the country from him. Can't beat that!

 

I also have the 3 87 tunes. according to the lie o meter it says i am getting 18mpg with the mileage one and 15.8 with the performance tune.. tow tune seamed to work decent pulling my car trailer and a full size van. I sure miss my diesel towing..

i did some data logging not sure what i am looking at. i did a dead stop to 1/4 mile run

ect=194
rpmdsd=592
fpdc=.28
frp=39.40
iat=94
load=.80
longft1=1.11
longft2=1.11
maf_v=650 low-800 high
rpm 4000max
shrtft1 .8-1.01
shiftft2 .8-1.01
spark 7.0-15.5
vss 84

 

the xcal3 tells you your gas mileage?

 

no I have a lariat with the message center hence the lie o meter. well thats what we called them on out superduties my diesel read 26 mpg and actuall was 18. just going off stock mode shown mpg to the custom tunes shown MPG

 

Custom tunes?? Wut is dis.??

JUSTIN emailed me and i need to send him my Serial # from my SCT so hopefully have some more news this week.

 

Cool. Keep us posted. And good luck!

 

Even if I lost, it'd be a helluva good time!

 

well justin sent me a diffent tune with less fuel and definaltly imporved the bottom end. I ony got to test it out on the 7 mile drive to work so i will give it a few days.. I will need to go back in and firm up the shifts to where i had them before.

 

Thats sounds like good news.

 

I travelled over 300 miles last night on my 87 mileage tune and didnt even use half a tank...My tank is 35 gallons, so with rough calculations (no Lie meter) I believe I got right around 18 MPG with all freeway driving And thats with 33x12.50 Toyo Mud Terrains. But I wont be able to tell for sure until I fill up again. I am a little sketched out after the tunes on whether or not my speedometer is correct though....And Im not sure how accurate the mile markers on the freeway are, but it seemed like I was going roughly 1.1 to 1.2 miles on my odometer to every 1 mile marker
