    I have read a lot on AIPs and back in 2008 when I started buying Tundras then sold them I stopped worrying about AIPs. Mendosy, SteveJ, and a couple others did a ton of R&D. So much SteveJ came out with a DIY 1.1 AIP instructions. Now that I own a 2011 Tundra DC 4.6 I now hate the dreaded loud pump noise in the morning and don't look forward to any possible failures.

    With that said, I am aware you have made a kit. So here are my questions:
    1. To get rid of the AIP loud noise can I just do the 1.1 AIP Bypass with a relay and resistor? .....if so do I have to block off the AIPs?
    2. My truck is a 2011 with 38,000 miles...with no issues at all, would it harm anything to install a Bypass without block off plates?
    3. In considering your kit, besides the price difference between buying a Relay with 87A terminal, a 4.7K ohm resistor and some wire, what would your kit enable/disable that the relay and resistor "DIY 1.1 Bypass" would/wouldn't do?

    Thanks a million

    mendonsy suggested I look at your Air Induction Pump Bypass Module - AIP Valve Bypass. I looked at your site and it looks like they're all for 2005-2007 models.

    Mine is a 2008 Tundra with the 4.0 V6.

    Do you have a kit for my truck?

    Thanks, Bob
