I am mainly looking to make the truck run as efficiently as possible with a good balance of power and efficiency. I will eventually tow a small-ish boat and trailer to haul construction debris but this truck will mostly be used for house projects and elk hunting. What are your thoughts on the tune? Anything else you need to know? Other than repinning, is there another benefit to going with this option/tune over a 0411 PCM swap?

Hi I have a two thousand damon daybreak motor home for the 454 gm. I'm interested in having the ECM tuned. Wondering if it's worth it and what is the time frame from when I take it out send it to till I get it back? Thanks keith phone number 6082145006

We definitely think it's worth it if you are looking to get some more performance out of your RV! We usually have a 2-3 day turnaround or you can purchase an exchange unit and send yours back in after for a refund.
Hi,
I have a 1997 Chevy Silverado K3500 with the Vortex 7.4L engine and 4L80 Transmission. I'm swapping to a NV4500 manual transmission. I have a whole junk truck to use the parts, but it has less equipment than mine, for example it has no A/C.
I have 3 PCM's available, the Junk Truck PCM, my K3500 PCM and an extra one I bought online before.
Would it be possible to tune the original Manual Transmission base truck PCM to support a fully equipped truck with A/C, power windows, power mirrors etc?
I can share the PCM's service Numbers if that help you determine which PCM will be a better fit.
Thank you!
Ernesto

As long as you can provide a functioning PCM that belongs to that truck, we can set it up the way you are wanting with manual trans and AC. The power windows, mirrors etc would not have anything to do with the PCM.
My pickup is a 1998 C2500 7.4L with manual transmission. Do you tune ECMs for manual transmission also?
( Mike Geiser, 03/31/2023 )
Yes, we do!
Yes I am wondering if you can tune a 0411 ecm for my truck to have a manual transmission mine had a 4l80e in it originally but I swapped to a manual nv4500.

No, we only tune the original "black box" type ECM for the 7.4L's.
