The tires are 275/65R20 which is a good bit larger. I have already up graded the trans cooler to 6.0. I have list of things but done know where to start.

 

Do not start with a tuner. Period. Start with exhaust, intake, get your truck scanned to see if there are any codes lurking.

 

I agree,thank you its not in the budget in the near future just got back from Disney World. How about the dp infinity tuner. By the time I would invest in gauges and a lesser cost tuner I would be at the same or more cost. I would like some input from those who have experience with dp. I do plan on getting the truck looked at before any modifications then the exhaust 1st.

 

What he said. Build up to it by laying the ground work so you can enjoy it when you get there. Intake, exhaust, gauges, FRx, and look for maintenance issues like leaking up-pipes, reseal the fuel bowl etc.

 

You haven't met Cody. His heart is so big that is displaces all the greed out of there.

With total respect... you are saying you have driven Cody's exclusive tunes for comparison? I've seen the data logs and/or ridden in trucks with tunes from just about every commercial tuner out there, and Stinky's had tunes from Jody, Bill, and Cody - but I won't get dragged into a public war on this.

I'm hoping Ziggy_15 got that from the Custom Tunes link in my signature, but if not - it's really worth a click to back jhl3 up.

 

Even without my tuner my truck is a beast at 1800rpm. I may be in first or second gear depending on the load but I never have a problem moving the load (the tuner helps me get it there faster). The stock programming peak torque is at 1600rpm so at 1800rpm you should not have a problem. I'm running just over stock size on the tires at 285/75-16 with the original 3.73LS in the rear chunk.

 

Too bad there is very little power being produced at that RPM. Pulling between 2400 and 2800 will yield the best results.

 

With the tires larger and that weight you need to leave it out of OD in the hills for sure.
And 2400 to 2800 is about right, I just towed that weight and that's where I towed mine. You also need a custom tow tune that makes your shifts stretch out where they should be. Something besides what you have, believe me you will feel the difference right away! I to wish Cody would do more tuning but there is a lot of others out there. Gauges for sure, you should already have them.

 

How about the dp infinity. It has the custom tune program and the gauges.

 

How about allowing some of the people that are familiar with both INFINITY and AE and/or TorquePro weigh in about the limitations of each so that you can decide which one or a combo has the most bang for the buck...

You may want to start a new thread: Limitations of INFINITY vs AE

ABSOLUTE loves his Infinity: has he used AE?

 

While I haven't touched an Infinity, I have a library of data from those who own one. Infinity is a programmer (not a switch-on-the-fly chip), OBDII gauge set, data logger, scan tool, and I think it still has a few gadgets like a music player (when connected to the head unit). It can work in conjunction with a chip (like the F5 or F6) if switch-on-the-fly is important enough to spend the money for both devices and tunes. Infinity is the heavy hitter for versatility in the cab.

The data recording is very fast, but much of the data in the logs is just repeated. When I pare the logs down to the raw data, I have to use one data point out of 4 - that means the unit is logging 4 times more samples than the truck is providing with our antiquated J1850 PWM protocol on the OBDII port.

As far as I know, only Jody tunes for the Infinity, so buying one "marries" you to DP for all your tuning. The Hydra chip has a number of tuners using this platform, and you can always "play the field" with this unit.

AE is a scan tool with OBDII gauges, data logging, service tests, and can adjust tire size for speedo accuracy. The data collection is a little slow, until one of us gearheads finally tinkers with it to dial the data logging speed up. No programming or tuning here. AE is the heavy hitter for servicing the vehicle.


Torque Pro is the bargain basement app with a lot of power and speed. I use it for an OBDII gauge set with data logging and programmable alarm set points. It's not much of a scan tool (yet) - you can't do a buzz test, KOEO, or a few other tests built into the Superduty 7.3L. It records actual data about as fast as the Infinity, but without all the repeats. No tuning or programming here either. Torque Pro is the heavy hitter for an inexpensive solution to gauges, logging, and alarms.

 

Yup , Love my infinity. It has AE in it already, but I bought AE before when I had an Edge system. My opinion, don't get the edge system. Works ok but they are prone to failure, stranding you god knows where. I went with infinity because of who sells it and makes the tunes, and because it comes complete with 18 gauges, of you choice, has AE built in, and it was a programmer not a chip. I'm not a fan of chips since my Edge ordeals, so wanted a programmer. Just a note, I wasn't implying that Cody is not a good tuner, I was implying that tuners are plentiful and they are all just as good as each other. I know no less than 20 people in my area that can tune just as good as Jody, Cody, Brian, anyone. Yet I chose DP because of there reputation and because they had what I wanted. I could have bought a chip, gauges, etc, but it would have cost the same anyway. I'm happy having it all in one little module on my dash. That said, I had a set of autometer gauges in my other truck, at 400 bucks for the set, they packed it in after 1 year. So I don't like expensive gauges either.

 

I have an infinity and love it, the only downside is you can't read the ABS codes, and I believe on AE you can. I also have the F6 and CEI hub so I can add guages that you can't see thru the OBDII port. It also allows me to switch my F6 tunes with the Infinity so I don't have a switch on my dash.
I have the older version of the Infinity i bought 2 years ago, so I'm not sure of any differences with the new model.

Also definitely click on the custom tunes link in Tugly's signature, it's well worth the read.

 

Without the ability to get into the ABS module, you can't adjust the tire size for accurate odometer readings. Big tires throw the MPG readings and the speedometer off in a big way.

 

I'm confused on this. Since monster tires don't change the sensor position or the diameter of the wheel it reads off of, then how do larger tires affect the ABS. All that sensor does is tell whether the wheel is moving or not. Not moving it starts pulsing, moving at a different speed then back, or vice versa, then it pulses, moving same speed, it does not pulse. So speed has nothing to do with ABS. ABS senses wheel slip, not speed. It uses speed or movement to sense this, but not the speed, but the difference in speed between all 4 wheels. So Wheel or tire size should have no affect at all on the ABS. Speedometer and MPG for sure. The ABS also has nothing to do with th odometer. Although of course the odometer would be affected because its traveling a different distance with different sizes. So get all that, but explain how it affects ABS since nothing changes for that sensor with BIG FOOT tires on there or go cart tires. Sensor is the same. Speed doesn't matter.????
