2011 5.3 liter AFM delete in DFW

2011 5.3 liter AFM delete in DFW

Postby Esteban [OP] » Aug 28 2019, 4:58pm

Hello fellow members,
I have just traded in my previous vehicle, a 2012 Grand Sport for a 2011 GMC Sierra crew cab and found out after the fact that the truck is equipped with the dreaded AFM, DOD. I have received two estimates from different Dallas, Fort Worth speed shops and was struck with sticker shock of the price to delete and tune. One shop said $3999.99 and the other shop came in at $4700 for the turn key delete. I figured it would be a little over $2k but boy was I wrong.
Does anyone know of a shop in Texas, or an experienced shade tree mechanic who could perform the delete any cheaper than $4k? I have a 03 ZO6 cam that I’m on the fence about using for this truck. I would prefer more low end torque than the peak power of the Z cam. Any info would be appreciated. The truck has 62,xxx miles on it now.
Thanks,
Steve

Why not just turn it off and wait till IF or when it fails or consumes oil?

For 4K you can throw in a performance engine or 6.0

Installing a delete just because and not wanting to have a nice cam is a bit silly.

First, "experienced shade tree mechanic" is a bit of an oxymoron.

Secondly, I agree with Mike.

Install a Range Device for about $200 and delete the AFM, or better yet, go with Lew, (www.diablewtune.com,) for about $400 and get a custom tune with AFM delete......and while you're at it, add a catch can. Prevention is key.

Nothing may ever happen to the engine, especially if you take measures to stave off problems.

I hear ya but I’m looking for this truck to be reliable over horsepower numbers. It already has TSP longtubes and stock exhaust. I would love to toss a Corsa Sport on the truck and call it good. That was my original plan. I’m going to get the OBD II delete plug and play module ordered ASAP as a bandaid for now.

Tsp delete kit is less than 1k. You should be able to find a shop that can do it for less than 3k labor

Also buy a tuner. Will improve shifts and throttle. the range can’t.

What makes you think the truck won't be reliable?
I bought my truck with 25,000 miles, and within about 6 months and 10,000 miles I added a Range device and a catch can. I think at the beginning of this year I did a "Lew" tune. I change the oil every 5,000 miles. I'm approaching 80,000 miles now, and the truck hasn't skipped a beat...I also tow a cargo trailer about twice a week...going up your way...BTW..

Well it turns out that when the longtubes were installed at Texas Speed and Performance that the AFM, DOD was tuned off on the dyno. This means that I am really only looking for a quality catch can at this point. The Elite Engineering E-2 looks to be second to none so that is what I’m going with. This does nothing but free up some coin for a nice catback exhaust. I was hearing some tapping from the driver side under light acceleration and found that there is a header primary in contact with the cross member or engine cradle. I will provide some clearance for the moving parts this weekend. I am not looking forward to that. Stocked up on bandaids.

Really don’t need a catch can on your engine. As it’s not direct injected.

But it doesn’t hurt
