CalSpeed & Performance offers custom computer PCM tuning for any GM based vehicle. We can provide a complete custom street tune for your LS based vehicle that is similar to our mail order tuning for your modifications. Whether stock or modified (cam/heads etc), we can provide with a custom tune that will ensure you vehicle performance is optimized. Based on the modifications to your vehicle we install a custom tune and further fine tune with you driving your own vehicle with our professional tuner on board. Tuning is recommended for most vehicles that are mildly modified with minor bolt-on type modifications. We recommend our custom chassis dyno tuning ($300) with wideband airfuel O2 readings for vehicles with moderate or major modifications (upgraded camshaft, cylinder heads or more etc).
***Not street legal, off road use only. For racing vehicles only*** Any modification to your PCM / ECM / TCM is not smog / emissions / CARB legal and will void your manufacturers warranty.
