well in all honesty around here the 2.5 is just local guys with a chip or efi an exhaust im a competitve soul an that would just destroy them with that the 2.6 has a few guys with work done but still mostly just the stock guys doing it or fun its mostly fair type pulls etc so it would be more competetive for what i got done. i got to admit see alot of ppl extremely happy with bullseye imma look into all routes
