Terminator X and Fast intake

By: Travis 04/08/2022

Installed terminator X in august of 2021 and started learning to tune the truck. HUGE improvement over the stock tune on the LS ECU! I like to tweak and change the tune slowly by writing the learn table if need be to the base fuel table about once every 100-200 miles. If I make significant changes, ie. leaning out idle or cruise I like to save as a revised tune ie V1,V2, ect. If something happens and the truck doesn't like my changes, I can easily grab the last revision that drove fine and upload to ECU and drive away.


Installed LSXRT intake and gain a significant increase in my VE tables.. that tells me without question the truck flows more air than before. Holley Terminator X fired right up and started adjusting its tune accordingly. I drove the truck very easy for about 100 miles and got a nice table to write the learn values to the base table.. Once we got a base tune established with the intake I started driving in lower gears, letting the truck turn some higher RPMs so the learn tables could reach more of the available cells. Once I got this all dialed in and adjusted some values for my cruise I took in account the average learned values and added some on my table for a full pull. Did some logging, had very successful WOT runs and she's running like it came from the factory this way today. Very happy with everything so far.
