Just finished getting my 350z fully tuned. 60k miles running strong.

Tuner told me most stock 350's came in with 215 to 225whp. Tuner ran a mustang dyno.

Run 3 was just bolt-ons (5/16th plenum, injen intake w/ velocity stack, greddy axleback, berk HFC. No tune on this run but tuner said it was running extremely lean. 1 whole point. Came in at 247whp/226 torque.

Run 2 was the car tuned on Osiris. Did it same day as run 3. Put down 260whp/237 torque. Not bad for some minor mods and a tune. Difference was night and day though in terms of driveability.

Run 1 was done a few months later but ironically, temperature was exactly the same (AZ) ran the car and it put the same numbers as a few months ago (Paranoid car was getting slower). Only thing that changed was I started using Lucas octane booster. Tuner advanced timing by 2 degrees initially but told me car didn't like it so we just settled at 1 degree. End results were 268whp/ 247 torque, I was actually pleasantly surprised by this, figured I would get virtually no gains from the Lucas. Biggest difference was torque jumped up 10ft-lbs from last tune. Butt dyno can feel a little difference.

Anyways figured id share my tuning story. Not sure if my tuner reads these forums ever (doubt it) but shout out to evan w/ estuned for a stand up job.

 

268 is pretty good - congrats
