Tuning limitsenthusiast estimates, crank hp on the stated fuel; sources: none named yet; method: the analyzer plans on the lower bound of each range
⚑Direct injection limits cam profiles compared to the old LS (community consensus). Calibration quality matters more than lobe bragging rights.
⚑Stock internals are commonly reported near 750 hp on sane boost (community consensus). The DI fuel system is the wall; port-injection add-ons are the fix past it.
04 The typical path
Intake → headers → tune → cams or forced induction. NA gains are modest on most platforms; the big unlock is boost, and boost starts at the fuel system.
