Can i tell if my RV has this already? Do you have identifying marks on the ECU? Interested, but don't want to buy one to find out i've already got it :D (my unit has 2 previous owners i think...)

Thanks!

It may or may not have a decal on the ECM depending on if they did a mail order tune or came in to our shop. The only way to know for certain would be to pull the ECM and send to us so we can read it out and check.
I have a 2000 C3500 with the 454/L29 and auto trans. The previous owner had the engine rebuilt in 2012 and tells me they installed an RV cam but I am not sure which one. I have the parts list and see one item called 01-412-8 hyd roller cam for $315. They also installed roller lifters, heavy springs and chain/gears. The heads, pistons, and intake are stock. The exhaust does not have CATS with dual to the muffler and single exit tailpipe. I installed a K&N replacement are filter in the stock air box. Installed E3 spark plugs which seemed to help. I tow a large fifth wheel trailer with RPMs between 1800 to 2500 typically. This is a crew cab, 8 foot bed. Is this enough information to create a tune or will you need more information? My goal is to improve torque and trans efficiency then MPG. The tire are one size larger than stock to the speedometer is off a little. When it shows 55 MPH your actually going about 57 to 58 MPH.

Thanks

Yes - We can definitely take advantage of the current modifications done to the truck and really help it out. We can also adjust your speedometer to be correct.
I am doing a cam swap on a 98 GMC K3500 7.4 comp cams telks me i will need a custom tune according to cam specs this truck is primarily used for towing plan to use stock fuel injection if posdible any info would be greatly appreciated ( Bob johnson, 04/18/2020 )
If you want to take full advantage of the cam swap then a custom tune will be needed to address that. We can easily do this with the specs you provide.
I have a 1996 Chevrolet K3500 what is 7.4 454. I’m doing a full build on the motor I’ve been told that these injections systems don’t do well with these kind of upgrades. If I send y’all Parts list of what kind of cam, injectors, pistons, etc. can you tune it Perform with these upgrades ( Dyllan Hunt, 04/09/2020 )
Yes, we can do that.
We would like to have ordered the 7.4 custom tune ,but appearantly you are out of stock at the moment.Is there any time frame when you will have more modules.I would like to send you mine but I need my vehicle.Also we would like to have had the reasonable price. Would we still get the good price when you get more control modules in stock? Thanks

We are currently out of clean/painted cases for the PCM's. With the shut downs due to the virus, our normal service company that does that for us is closed. If you don't mind a "dirty" PCM case then we can take care of an order for you. Please contact us directly to set that up at 800-417-4559.
