Disappointing dyno results 370z 7at

Taylortoons

I had my car tuned at Uprev in Austin TX. The top end gain was 4hp from 282 baseline to 286. In the middle of the power band, I picked up 10hp. To be honest, I was super disappointed with the results as I was expecting an improvement of up to 20hp.

The tuner told me that about 5hp on the top end was normal for the AT and that a 20hp gain was impossible for these cars.

In my experience, the tune was not worth the expense. I needed it to clear the codes created by my 4.08 gear upgrade.

If you have added standard upgrades like intake, TP and exhaust, you don't need a tune. The ECU will adjust properly to accommodate the improved air flow.
