I mean really dude…. If MPFI and OD is all you’re after just put the L29 in it and call it a day. You could spend the savings on another square.From what I’m seeing, it’s insanely expensive to tune and add functions to. Spear tech mods the harness and can tune the ECM/TCM for only $3,950 plus S&H. The L8T/6L90 are $10k engine, trans, harness and ECM/TCM. It’s still not bad considering the drivetrains have under 20 miles and a GM Connect and Cruise L8T/6L90 is $19k. The LT stuff requires a $500-$700 license fee to tune the ECM alone.
But the L96 6.0/6L90E is not only cheaper but WAY easier to tune and modify. Plus it’s proven platform for reliability.
L8T is about $16k installed 401hp 460tq
L96 is about $9k installed 360hp 380tq
I’m trying to figure out if the extra power is needed. I’ve never driven a 6.0 crew cab dually. Stats are similar to the smog 454 in it.
Im still considering buying a vortec 7400/4l80e to swap in.
My goals are adequate power, OEM multi port fuel injection and overdrive.
If you want something rad do the big LT and 6 speed.
