Ok guys needing some help for my TRX. I have already order some parts but I’m trying to get a grasp on the pulley system and it’s a little different for me since I come from the turbo world. I’m hearing different story’s on what’s better, meaning the upper and lower pulley. Is it better to just change the upper, or just the lower, or both.
The parts I already have are:
Id1300x injectors
Killer chiller
180 Thermostat
Jlt catch can
Now none of this is installed yet, but the catch can, but I’m just waiting on some info about what pulleys to run. For a tune I will be doing a 93 pump gas tune and also a E85 tune. I do appreciate the help in advance, thanks again guys.
