Yep, I can't take the chance of voiding my warranty. I am going to get an air intake kit though, I figure I can remove that without too much hassle and little evidence left behind. I'd like to get a lower pulley also, but I don't want to install a chip and leave the contacts obviously cleaned. The truck is fast enough for me for now but I am intrigued by the increased blower whine from the air intake kit, plus the added power.
What's more is I bought an extended powertrain warranty to 50K miles! It's going to be a long wait!
Then again, with my commute, my warranty will be up sooner than I think.
Warranty here too! I didn't purchase the 6yr/75K extended just to get it voided. With just 18K on the clock, I think I'll make it for the full 6 years (IF I still own it!). Still have another 3 1/2 left!
