{Garbage-Tuning Box} on a X15

[Rawze]

If you want more pep and to actually "Wake it up" per say, ... then maybe start by getting rid of those garbage 3.36 rears that are geared too tall for hauling anything but a bunch of flowers. - It is far cheaper re-grar the back end properly for what your hauling than trying to make the most expensive thing in the drive-line work harder (the engine) to make up for a s#itty set of rears that are designed to lug the engine do an agonizing death below 1500 RPM's.

With 3.36 and taller ears, the truck won't get out of its own way compared to something geared more appropriately .. even at 600HP, once you put a heavy load behind it.

Here is a chart ...

And if your other truck is de-mandated, then you need to have the program copied out of the ecm and e-mailed to me to have it looked at ASAP, to ensure it is not causing progressive damage over time. More than 90% of all delete programs are extremely harmful to the engine. Again.. a laptop and an inline-6 adapter is needed. Might as well be running sand in your oil otherwise.
