no.
pre Lci's make less power than LCi but all f90's put down ~590-620 to the wheels.
account for 10-15% power loss for transfer of energy from
motor to trans to diff to pavement.. all f90's make over 650 at the crankshaft.
his tune gives 100hp at the crank via a simple boost in psi from turbos.. very standard.
piggyback tunes are garbage however by nature.
spend $1500 on a flash or go home .
get what u pay for |
So your saying what bmw advertises as 600 crank horse power inaccurate?
