Hello Everyone,
I'm new to HP tuners but not new to cars or computers. I just recently purchased a 2009 Tahoe with the 5.3 and after reading a bunch decided I wanted to disable the AFM to help avoid lifter failure. After researching what it would cost and what I wanted to do I decided to purchase HP Tuners and do it myself. Now I have all the capabilities of HP Tuners at my disposal and I'm wondering what else I can do to make this thing more efficient run better, etc. After doing some research it seems foolish to even bother with messing with the fueling and timing without a wideband.
Is there anything else I can do via HP Tuners that doesn't require a wideband? I'm not against getting a wideband but I don't really want to do a permanent install of one on the vehicle and all the clamp on ones says to only use on dyno runs and not for driving around the streets. Since this isn't a high HP car I don't really want to pay for dyno time. Has anyone here installed a permanent one on a Tahoe/Yukon/Escalade etc? I looked under the vehicle and the way the Y-pipe is it seems damn near impossible to install one before the cats unless I put it right next to the stock ones?
Thanks for any input on this.
