MP122 Magna Chargers are recommended
for bored and/or stroked LS-series engines with 6.6L
or larger displacement, or smaller highly modified engines. 
Installation on stock 5.7 and 6.0 L engines
can produce unsatisfactory throttle response.

your installer/tuner will custom-edit your PCM calibration files

for your specific application.
