I have a complete K&N air filter kit ready to put in my truck, 2007 Silverado, and then going to put dual exhausts on it. I called the dealer's Svc Mgr, he's ok with it re warranty. I know from doing the above to my last truck that the power is better after the filter and exhausts, no doubts about that. It seems intuitive to me that if the truck has more pulling capacity or power at the same rpms after the mods, that it ought to be able to pull a hill at lower rpms and therefore use less gasoline on that hill. For you car guys out there, does more power = more miles per gallon? (These gas prices really chap my a$$.)

It does, however the flip side is that more power used incorrectly will result in worse MPG. More power will enable you to run at lower RPM's thus using less fuel. But the heavy right foot syndrome that is associated with having more power at your disposal is what will hurt you. Also you need to figure out how much fuel you are saving compared to what the cost of the mod's are. Most of the time you are only going to get 1 maybe 2 extra MPG out of the mod's that you listed. Depending on how much you paid for them. 1-2 MPG extra takes a while to make up for $500 in mod's to get them. In any event the less restrictive aftermarket exhaust should flow better keeping you EGT's down when towing and will help give you more life out of the motor.

Don't know if they make one for our trucks but, an over-under gear splitter would help immensely in mountainous areas in regards to fuel mileage and just plain having the right gear. But then payback on the investment would probably never be realized.

I don't think that it would be cost effective to do anything with the gears. Unless you are running some bigger tires, I wouldn't mess with them.

I installed a Hypertech chip in my truck, it seems to have given me about 2 mpg...but when you need the extra HP is nice too. It also allowed me to move the shift points to keep the tranny from "hunting" in and out of OD...

I would look at some of the truck forums and make sure that those modifications will in fact, increase your fuel mileage. My research is showing that it is not always the case. The engine speed will not change at a given roadspeed in the same gear no matter how much more power you make. The advantage to having more power from a fuel economy perspective is that the transmission may hold in a higher gear when pulling a hill rather than downshifting which would then increase engine rpm. You may be better off investing in a programmer and installing a better tune for the engine and transmission.....JMHO....GOTT

Thanks for the replies. Is a 'programmer' same as the hypertech chip OD put in his truck?

Yes, they all do roughly the same thing. Very similar to the power commander or dobeck that we put in the machines. With a gas motor you will not be able to do some of the stuff that programmers do for the diesel trucks, but they will in essence add HP by "tricking" the computer on the vehicle. They are kind of nifty because you can also change various engine parameters ie, raise top speed limiter, adjust tire calibration for different sized tires, check and clear trouble codes and such. The edge evolution does all this and also lets you view a wide variety of engine parameters. It plugs right into the the oem diagnostics port and has adjustible power range. EGDE EVO

The absolute best programmer for gm vehicles is the EFI Live. If you want plug and play then go with the hypertech or edge evo. They are simple to operate and safe. The biggest gain is going to come from changing shift points in the transmission. If you can keep your foot out of then drop the shift point for OD and just cruise. It will help eliminate the unwanted "hunting" for gears up and down hills. If you want to really get down and control timing, fuel maps, etc then EFILive is the way to go. It is probably not worth the money if you don't plan on doing a few other mods to the engine.

EFI live is great for someone looking to make 700hp or to custom tweak the motor, but for a guy who wants to just make a few extra ponies for MPG and not smoke your tranny, I don't think it is the best choice. Also it is by no means plug and play, and having to either pay someone else for a tune they wrote, or take a gamble and install one that you know nothing about would make me stay away from it.

I agree zac41. Plug and play is much more useful for gas engines unless you are going for extreme hp and mods.

Should the programmer be installed after the K&N/dual exhaust mods?

For the most part it wouldn't matter much if it was installed before or after. It is not the same concept as for your wheeler where you add one and need to add the other at the same time. You could add just any one or all of them to increase performance. None will hinder your performance alone.

Which programmer did you decide to go with?

Advance Auto here handles Hypertech, going there tomorrow and get a price. The gains in hp and torque are about the same as Edge. I like the fancy display on the Edge unit, $450 plus shipping.

Still think that the tallest tires that will fit will help MPG the most. But not the heavily lugged mud tires. You want as tall and as light as possible. It will throw off your speedometer to the per-centage it will increase MPG but it's not hard to recalibrate in your head. COMPARE TIRE REVOLUTIONS PER MILE, OLD TIRES VS NEW TALLER TIRES. Usually tire dealers should have the rev/mi. If not look at the TireRack.com site. The per-centage difference is what you are looking for. You will lose acceration to the same per-centage, but if MPG is your goal it shouldn't bother you. And forget about taller aluminum aftermarket wheels. They weigh a ton and you lose more than you gain. ...take 'er easy old buddy. I was cruising web siles and jumped in Aurora to see whats happening. getting back into fishing with new boat. My MAX hasn't been even started in 6 months, I'm ashanmed to say. Mainly health and general in-activity issues. Thank God for Gov. Palin, our next VP. Obama is dead! Long live the queen.!

Embarrassed to say that it's been in the garage for 3 weeks and I'm not done setting it up and waiting for ordered parts to arrive. Since I hit 70 I just don't have the get-up-and-go I did all my life. Very frustrating. Thankful that my wife doesn't nag. You guys all take care of yourself now. Life is too damn short. The weeks just fly by when you get old. Seems like every other day is Friday. Sure didn't when we were working all day. As to the fuel economy improving, even if you get 3-4 more MPG it will take years and years to recover that $500. Many times it's cheaper to sell the truck and buy a smaller 4 cylinder that can tow your requirements. You could probably double your MPG. God speed, and vote Republican.

Hey Turbo, good to hear from you. I'll take your advice to heart as I know you were in the mechanical business for a long time. Also, I take it your health has improved, you weren't able to work on a boat there for quite awhile. As for Gov. Palin, I liked what I saw and heard of her, I think she's a 'go for broke' proposition for McCain. BTW, I'm pretty sure most of us are on the same side of the legislative aisle as you are. Stop by more often, stir up the troops!
