Anyone working on tuning?? - Toyota Yaris Forums

Don't get offended by what I'm about to say if you disagree.

Saying there isn't any power potential in the 1NZ is bullshit. We have established this already. Someone is running around putting 180 to the ground in a Yaris on stock internals. Nobody will know how much the Yaris will or won't handle until ZPI's car blows up. PERIOD.

In the meantime, Ashley hit the nail on the head. If you want to see power our of your N/A Yaris (re: if you can't afford a turbo) you're going to want to start bolting on some less restrictive parts, then go out and give your car a good tune w/ a piggyback. From the graphs I'm looking at, 15-20% looks to be conservative. I think 115-120 on the ground from a Yaris with a relatively small investment is feasible, and a 20-25% increase in horsepower over stock isn't going to cut your engine life in half.

The power potential in this car lies in the restrictive intake/exhaust hardware and the gas-mileage-only stock tune.
