I had substantial increases in throttle response, tuning, fuel economy, and the overall performance of the engine increased marginally over the entire power band.
It also removed the shuddering the car used to do when at low rpms.
Tuned with a wideband o2 sensor and a dyno, painless and worth it IMO.
Or the fact that a CalumSult basic is dirt cheap and can do a better job at tuning....
Never mind the realtime ecu....
I know the tune Im running in the NX right now, on a basic board, gave me 10hp almost everywhere under the curve. 10hp for under 200 dollars including dyno time. On a motor without a header or exhaust, just a WAI and POP. Personally i call that bang for the buck
