Hi !
We did the LF3 last year in XTS and last month in CTS-V Sport .... stock trq in CTS-V Sport is way higher then XTS but both same engine power ... got 420PS engine power and nearly 500PS engine power with 91 okt Arizona pump fuel .... by IPF ... but gearbox Tuning was nessesary to have perfect drivebility on the road !
torque you can increase at this engines up to the moon ... but if the drivetrain can handle it ... thats the big question !
any request for LF3 Tuning send to our IPF-Tuning staff !
greets ASH@IPF-TUNING
