Trouble Codes I'm getting GM Codes P0171 and P0174, which means that the engine is running lean in both banks 1 and 2. One would assume that this is a result of the Cold-air intake and the TBS, but I'm about half way convinced to just take them off of the truck and go back to factory. Any...

That's the weird part... and perhaps this can shed some light for you guys as well. When I get into the throttle, the check engine light does come on. No other time though... not at idle, not when normal driving... I've got no freaking clue what's going on...

Do i have a freaking lemon... or do I not know what I'm doing? In my life, I've had five of these 'projects' and not one has had a decrease in torque once I was done with the bolt-ons. Seems to be everyone elses opinion on here as well... If I meditate, will that help my frustration?

My concern is this: Even if it's not supposed to make a big difference, it should never give you less torque, should it? I knew I should have paid someone to do this crap... -Seriously frustrated-

Guys, Still having some issues, and your expertise/opinions would be greatly appreciated. The low-down is that I put air intake and a TBS on my ride about two weeks ago... Now I feel like I have much less acceleration on the highway. Not to mention, I have to give it much more pedal to...

Will having my Yukon 'custom' tuned help me get some of the pep back on the hwy?!? Since I put a TBS and an air intake on my truck, I feel like I lost some major torque... Any ideas would be greatly appreciated. Thanks boys.

A difference... That's difficult to say... I definitely notice a difference in the whistling sound coming through the hood. The part of me that remembers taking almost half a day to install it would looove to tell you that I noticed a HUGE difference, but I'm not sure I have. The only...

I reached underneath the TBS, where I thought I could hear an air leak, and it felt like it was going to suck my finger in... That's when I decided that that could be my problem. I went and bought gasket paper, and cut my own piece. Seems to be working fine. Thanks again!!

Thanks for all the replies guys... I left work today a bit early, and I was actually able to trace down the problem (I think). The gaskets that were sent with the TBS were brittle, and had broken on the bottom of the spacer where I couldn't see. Today, when I did a leak check I found it...

Boys, I'm in need of some help. I put a TBS on this weekend, and I have been having trouble since I tightened the last bolt... Symptoms: 1.) Check engine light is on. 2.) Smells like the truck is running (very) rich. 3.) Temp is running right at 210. 4.) Feels like there is little...

I'm putting them both on this weekend, so I really appreciate the tips. Hand cramps, here we come! I'll post pics when I'm finished... Thanks!!

Air Intake Questions When trimming the shroud and fan blades, does that have any negative effects on cooling, mpg's, etc? I'm getting ready to do a lot of work to my Yukon this weekend, and I was unsure of the impact of trimming the fan blades... Also, what did you use to trim them...
