Well guys so far my LO3 has the mods from my sig done to it and it can be pretty rough on the low end while trying to cruise, kinda like a hesitation but not violent. I am running stock fuel pressure so do you guys think its time I break down and buy a JET regulator and a guage set-up? I just know that even without tuning that it should help a little giving it more fuel. Thanks for any extra thoughts you can provide guys.
