My friend just got his L99 back from SP. Made 347 on a mustang dyno(reads the lowest).
Mods:
Pipeline intake
SLP Loudmouth I exhaust
Diablosport Predator
First pull made 311whp(stock tune), second pull made 334(Diablo 93 tune), last pull made 347(Jerry's tune). All numbers are uncorrected so factor in a few additional HP for SAE.
