    Do I need Engine tuning? Where R they?

    Does anyone know of a Dyno\Engine tuner in the Canada, Southwestern Ontario area?

    Mods I have are Underdrive pully, Predator tune, Ported TB, Ls6 intake, Lid+K&N+Bellows+Free mods, TB full throttle Voltage TPS. Do I need a dyno tune?

    I guess I should ask, do you think there is a chance it will be running to lean, since I have introduced more air, and increased flow and advanced timing, but have not changed injectors or tuned for more fuel?

    yes you could be running lean. But it shouldn't be dangerously too lean. There are many people driving around with headers and no tune.

    Yes you are right, headers will cause an engine to run rich. I didn't type a complete thought. lol As far as running lean- you only have a ported TB and a LS6. Those will both increase the airflow into the engine, but not soo much that it will lean it out significantly. I have both on my car and it runs great. And i am driving on completely stock tuning.

    While a tune will benefit you right now, i wouldn't get one unless you are done with modding. A tune will likely run you $400+ u.s. If you plan on getting headers in the future, or something like a cam, then wait until that work is done to get the tune. You will see much greater benfits from a tune then. Hope this helps!
