A dyno tune, which involves remapping your SUV’s electronic control unit (ECU), typically takes 2-4 hours. This is a software upgrade/tweak, so the tuner will probably not be installing any parts.
You may decide to follow up on Stage 1 tuning. In Stage 2, your tuner/mechanic would then turn their attention to your Caliber’s air intake and exhaust hardware, customizing them to achieve your hp goals.
One of the best ways to improve engine performance is by having your Caliber professionally tuned—-but a Dodge Caliber SXT tuning takes money, particularly if you’re having it done by an expert. You need to budget for it.
