Been trading emails half the day with Torrie on getting some tunes for my FX4, He has been fantastic, I am stunned at how fast he has responded to my emails, almost like I was the only one he was working with!

My handheld is updating while I'm typing this and as soon as they hit my inbox, i am gonna load the 87 tow tune he put together for me. Thanks to all you guys who posted about Unleashed, looking forward to trying them out! Gonna load the 87 performance tune in it first!

Hey guys!

I have put further tuning with Torrie off until my intake, charge pipe, and new tires were on. Good news! My truck is now complete for the time being and I literally JUST emailed torrie with a 0-60 WOT log, so I should be hearing back shortly . Now, everything includes...

AFE Strage 2 Intake (oilless)
AFE Charge Pipe
AFE 4" Cat-Back Exhaust (black tip)
SCT tuned - Unleashed 91 (will be moving to 93 when torrie and I dial in the 91)
Leveling spacer (the solid alluminum type)
275/65R20 Toyo A/T 2
BOV to atmosphere
35% Window tint

Also, my truck has the 3:73 gears, so I actually like the ratio with my 34's better than the stock 32" pirellis...

How did you do yours? How long have you had it this way for? How does it sound. I'm in the process of doing this.

The sound is cool, blows off every time you let off the gas though - more boost means louder "PSSHHHH." It IS a bit "ricey" but I have always loved turbos and I am not ashamed to say I like it. Although, once the cool factor wears off I may change it back. Only cost me $50 to do it and take 10 minutes to put back to stock.

So, update...

My SCT magically decides that it is no longer married to my truck and SCT is closed until Monday. Perfect timing.

I'm getting a tune as well now.. Looking forward to it.

Not had a whole lot of seat time in the truck with Torries tune in the truck, but my initial thoughts were when I did lay into it a few times, it felt stronger than the canned 93 tune that SCT gives you!

Thanks for the posts guys!

So, even though my SCT now thinks my truck is an impostor and wont tune it, it is still running with the Unleashed tune so I am good for now.

I wasn't expecting much of a power gain with the intake and charge pipe, like maybe 5hp over my Airaid... but HOLY SH** this thing really scoots now - more so than before. Not sure why, I think the larger tires may have something to do with it? I know, I know... not likely - bear with me....

Is it at all possible that larger tires on the 3.73 geared f150 could IMPROVE acceleration? Since as long as I can remember, I have known that larger tires means more rolling mass and less leverage from the motor which means less power. HOWEVER, the truck feels much faster and I have a theory...

My theory is that 373 is too low of a gear on 32" tires and these trucks cant fully utilize their massive amounts of torque at that ratio. SO, with larger tires, power would normally decrease, but these trucks are so torquey (500RWTQ) that the taller tires don't slow down acceleration and in fact take larger "steps" (larger circumference) per revolution of the tires. Thus, same rate of acceleration (in regards to RPM) with larger steps via the taller tires = FASTER?

If I am smoking crack, please tell me... because if I heard someone else theorize that larger tires = faster I would tell them they were smoking crack. The truck is noticeably faster and this is me trying to find a logical answer other than a charge pipe and intake adding 20+ HP (very unlikely).
