    But forgot to finger it! :blush2:

    Installed the blocker plate today. Drove the truck about 25 miles to Lowell and shut it off for about 10 minutes. Start her back up, presto CEL. P0401, Insufficient EGR Flow. Durrrrr :cuss:

    I did however notice an immediate increase in throttle response and according to the DIC (i know i know, just using as a reference), I've gained a tenth of mile per gallon.

    I guess I should get off my tail and block mine.

    That blocker plate is a cheap and easy modification that really makes a difference.

    That's what I'm planning on doing eventually. However, I need a bit of help guys. I'm trying to install my MBRP front pipe that I got from Kyle at XDP (thank you Kyle!) and I can't get the damn converter past the crossmembers. Do I have to lower the trans crossmember to get this beast out?

    I never blocked my 04 LLY. I havent blocked this truck yet either. I've heard of too many people losing mileage by doing so.

    Nope. At least not if it is the same as my '04. You just need to remove the hanger bracket that comes off the side of the transmission. You should then be able to twist the converter pipe around and take it out toward the front of the truck. Its a tight fit, but it should go.

    I've done it on an 05 and it is a tight fit, but you won't have to move any crossmembers.

    Finally got it out. Took me forever to realize that hanger bracket unbolted off the transmission.

    And WOW, what a difference. B!itch is loud as hell. :devil:

    One more question. Is it possible to bolt up the front pipe a little off center? I think I may have but I'm not sure :blush2:. The clamp looks like it's tighter and in a bit of a different position on one side than it is on the other :wtf:

    That front clamp can be a bit tough. I didn't notice a big change in sound when I changed mine out so maybe you didn't get the front clamp sealed up just right. You should be able to feel around the area with the truck running to see if you can feel exhaust gasses blowing out. I swap mine out with the converter each year for inspections, so I've had some practice with it.

    Definitely will have to check that because something isn't sounding right...

    PPE's tuner has tuning in it that turns off the egr cel. I had a superchip in and unplugged the egr and the cel was on all the time, then I swithed to PPE and and blocked the egr. Now CEL free.

    I was thinking about getting a PPE programmer to get rid of the light, but I'm holding out for EFI Live.
