#216 of 245 Re: any problems with k & n filters? [jmath53] by moosealanche05 Sep 11, 2007 (1:54 pm)
Replying to: jmath53 (Apr 04, 2006 3:05 pm) jmath53, I have a 2005 Avalanche 5.3 L with the K&N #77, and a PowerAid Throttle Body Spacer and had no problem. If you have an electric radiator fan you do not have to trim the tubing. This set up works very well when combined with the Stainless Steel MagnaFlow Cat Back Exhaust. I am getting 21 MPG on the highway when I set the cruise 75 MPH. Not bad for a big truck.
#217 of 245 HyperTech Tuner For Avalanche by moosealanche05 Sep 11, 2007 (2:08 pm)
I was thinking of purchasing a HyperTech HyperMax Tuner for my 05 Avy and was wondering if anyone out there has one? If so what was your experience? Any noticable improvement? Worth the Money? What settings did you use? Do you know of any fourms that discuss the Tuners for the Avalanche?

#219 of 245 Body Filler Question by avalanche5 Nov 14, 2007 (7:38 am)
My friend & I were going to try to fix a dent on his 89 Camry. I was looking to buy some body filler but I am confused as to which one to get. Anybody have any opinions on which of these would work best?   http://www.autobodytoolmart.com/c-499-body-fillers.aspx?cid=FM1
#221 of 245 V-4 / V-8 mode by 07av Nov 25, 2007 (12:11 am)
I just bought a '07' Avalanche..... "LOVE IT"  I'm looking for a way to keep the V-4 mode in a little longer?..as soon as any gas is applied, it goes into V-8 mode!  When I'm crusing, it's on V-4, but 'any' throttle,it jumps into V-8 mode! I think if it stayed in the V-4 mode just a little longer, it would save a little more gas? Anyone have a FIX?

Replying to: 07av (Nov 25, 2007 12:11 am) When you're cruising try using cruise control, this might help with the mileage. My son has an 07 Silverado and the Active Fuel Management doesn't seem to add but maybe 1 or 2 mpg at best.
#223 of 245 better motor and rear end by deano16 Nov 28, 2007 (8:48 pm)
i am looking to buy an 07 avalanche, is there an advantage or big difference in the 5.3flex fuel with 3.73 rear end and the 6.0 with the 4.10 rear end? difference in mpg and will flex fuel be big help in future.

Replying to: 07av (Nov 25, 2007 12:11 am) From what I have researched, you are stuck the V8 to V4 modulation based input to the CEU. I have an '07 LTZ also. The best advice for keeping it in V4 is to "lift" your foot a bit. Quite frankly, I think the MPG I get is remarkable considering the size, weight, and wind resistence one has with an AVI. I get 16.5-17.2 MPG City and 18.8-20.4 Hwy. That is a CONSIDERABLE improvement over my old '02 Z71 AVI.   I see comments about using cruise control for better economy....nonsense. It's not going to happen. A CC senses changes to grades that are probably not sensed by the average driver. On any grade at all, the CC will punch the trottle down which you might not be prone to do with your foot and you'll see the Instant Economy drop like a rock.

Replying to: rocky07 (Dec 04, 2007 2:36 pm) thanks, I have found that I can get better economy without the cc on also! I was hopeing that someone made (or) knew how to override the CEU, to up the transition from V8 to V4? I know they have plug ins to change shift points and other things to the computer and wondered if it could change the V8/V4 mode also, BUT, I guess not? maybe someone will later Replies to this message: rocky07 (Dec 09, 2007 11:37 am)
