LBZ EGR Blockoff and Fingerstick

cs-john · 02-14-2007, 04:31 PM

I recently purchased a PPE Xcelerator and EGR blockoff with the module (fingerstick). After talking to some friends and local dealer mechanics, they said the blockoff will raise the exhaust temp and reduce power.

I find this confusing since the guy at PPE said it will reduce EGR's. Can someone with some expertise clarify this for me. Thanks.

most local dealer mechanics don't know what they are talking about. PM 05LLY (moderator here). He actually had the stuff installed on his truck. Blocking the EGR valve stops exhaust gasses from entering back into the engine. I would call BS on this. You will be running higher boost with the PPE programmer so your EGTs should go down. I would still install an EGT guage though so you know how hot you are getting.

Thanks. The Pyrometer is on my list. I'd like to get the piller mount but the ones I've seen don't offer a single gauge. The one's I've seen are 2 or 3 holers.

THe blocker plate will lower egts due to the exhaust no longer going back into the intake. as well as keep soot out of the intake side of the engine. you would not beleive the amout of soot that will collect in there in just 8000 miles!

There is some truth to it loosing power when you install the blocker due to the p0401 code that will set. THats where the fingerstick comes in, it keeps the codes from setting and causing defuel!!!!!!

i have an 06 extended cab 4 wheeldrive duramax i have an hypertech hyperpac a banks ramair kit and a magnaflow turbo back 4inch exhaust kit on it. the truck has run 14.84 in the quarter but it did not have the exhaust kit or the banks kit on it then. i keep getting a code saying that the egr valve is not working right, it has been replaced once and now its doing the same thing that it was doing before the dealer replaced it. it just wont run like it used to. i took it to the track last weekend and the best it would do is 15.86. if someone could help me i would appreciate it.

Im thinking about ordering the banks sixgun with the pda.Just wondering if anyone has had any dealings with the one that just came out for the 06 duramax.

I've decided against installing the PPE EGR blockoff plate and fingerstick. If anyone is considering one, make me a reasonable offer.

will this work on a 05 LLY?

cs-john · 04-05-2007, 08:05 AM

I don't know for sure but I would guess not since the box is marked LBZ. Maybe someone here would know.
