Hey all,
I’m about to pull the trigger on an L87 engine locally, to put into my 2016 Escalade. I believe it shouldn?t be an issue getting the L87 running on my stock ECM and harness, can anybody confirm this before I hand over the cash? Appreciate any insight!
Don't do it. The L87 is DFM, you can't control DFM with your computer. Plus the block is completely different on a L87 compared to a L86. The valve area with the DFM is all different.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I’m planning on a DFM delete, and I’d be getting the engine fully dressed, does that change things?
Should have quoted the reply sorry. If I’m doing a DFM delete with cam, and receiving all accessories, intake etc, just no harness/ECM, would I be able to run it on my E92 and stock harness with a tune?

I've seen/heard examples of people pulling vacuum for the brake booster from the PCV lines, so if that works it would be a simple solution. But I'm new to this, just trying to figure out the best route for replacement of my L86. It's either this L87 if it works, or an L8T instead.
It can totally be done. I just took out my L83 and put a L87 into my 2015 Silverado 1500
