Joey Mack Posted 23 hours ago Share Posted 23 hours ago Actually, there isnt an EGR on an AI. Its a bump on the exh cam lobe. The exh manifold is restrictive along with the ECU program. It does a lot of math and only delivers enough fuel to keep from being a rolling road block.. you can change the gov setting from min-max to allspeed and get a little pep in the step but, thats all i know. Smarter guys than me may know better. Quote Link to comment https://www.bigmacktrucks.com/topic/75020-2007-granite3mpg-avg/page/2/#findComment-566949 Share on other sites More sharing options...

JoeH Posted 8 hours ago Share Posted 8 hours ago I think there was some political animosity that led to a series of people getting sent down the road. Sad, he was an absolute wealth of knowledge iirc. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75020-2007-granite3mpg-avg/page/2/#findComment-566980 Share on other sites More sharing options...

Popular Post The Heinz Posted 7 hours ago Popular Post Share Posted 7 hours ago At least it's not an ASET AC, with an EGR cooler that always teeters on the edge of unavailability, EGR temp sensors built into the mass flow tube so it costs upwards of $1300 for a new one, a VGT that uses air to actuate and has dinky little filter on the bottom of the block, the list goes on. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/75020-2007-granite3mpg-avg/page/2/#findComment-566992 Share on other sites More sharing options...

I have not looked for a hp tag on the engine. All I know is these were originally to be sold to ABC building supply but the deal fell thru and they got a good deal on a batch of these after the frames were shortened for use as a tractor.. I'd suspect it was built as a cheap low hp fleet spec truck design to Hau maxl 50k gross. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75020-2007-granite3mpg-avg/page/2/#findComment-566994 Share on other sites More sharing options...

Unless they were pickin on tjc, and knocked his ice cream out of his hand.. not my ice cream, my jack and coke!!! the rules here are pretty hard to adhere to, which everyone currently knows. not all, but the important ones: Any member that willfully trolls or tries to instigate other members will receive warnings but may also be banned at anytime! No nudity or shock imagery (gore) - It is safe to post photos that are no worse that what you can see at a family beach. Do not post anything illegal, hostile or threatening. Name calling, harassing or threatening other members will not be tolerated! Disrespecting forum moderators or admin as well as failure to follow any forum guideline and/or rules will result in warnings or bans! the bottom two are the ones that were blatantly disregarded causing the mass cleanup. then when you come back with another username and start rite into calling out the site and moderators, well, you get the extra large ban hammer. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

tjc transport Posted 5 hours ago Share Posted 5 hours ago now back on track: we had 5 at the old company. 427 with the Mack 8 speed trans. gutless wonders. but they were only gutless wonders because the shop manager (owners father) was a firm believer turn the engine down and they will last forever. so he had them detuned to round 300 HP and they also got 3 mpg. i tried telling him numerous times if he turned them up fuel consumption would be cut in half, but he refused to listen. so i stayed in the 79 DM 800 with the juiced 237 i tuned myself and got 6 mpg out of. then i went to the current job and a few years later we bought the 05 granite. 427 engine with eaton 8 speed. but this one was set up properly and i was getting 6 mpg even with the highway gears in it. dont know how fast it would run, but i could easily do 75 in 7th gear. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

I do believe the ami-370 is a great base to build the delete off of! Can you check his software update level? Step 12b I think is the critical update for the vecu if I recall... Start with a boost gauge that is most important to see if you're even hitting fuel boost. Post pictures of your exhaust manifold on the truck. Should be able to see pretty quick if it has the restrictive manifold. A top view I think is most helpful. The whole EGR delete can be done by swapping the exhaust manifold, turbo, and exhaust pipe.

Joey Mack Posted 56 minutes ago Share Posted 56 minutes ago Bud, he has the ASET- I. There is no EGR valve, and only a bump on the exh. Lobe that allows some exh. To be sucked back into the engine. Ues the manifold meeds to go, the turbo swap sounds good. ECU program as well.
