Dyno Tune vs E-Tune, 15whp Gain
This 2006 350Z came in running an Uprev Osiris E-Tune along with aftermarket intake and exhaust. The baseline dyno on the e-tune revealed the air fuel ratio was too rich at 11.5:1 and the timing was overly advanced to the point of slight knocking. After Hal cleaned up the fuel and timing maps he was able to move onto intake and exhaust camshaft tuning. The final result was 248whp, up 15whp from where it started. This is the perfect example of why you should have your car dyno tuned instead of an email tune.
