need advice
 

I have 2008 silverado LT regular cab . both AFE air intake system and Borla exhaust system installed so both air system and exhaust system has been modified . therefore i decided to recalibrate (tune) the air fuel ratio to get the best result . Can any body advice me what is better to do if I buy the calibrator and make the tuning or take the vehicle to the dyno .

waiting for your replies .

If you aren't a professional, have one do it.

Personally I use a Superchip hand held programmer it does what I need for towing and lets me change back to a mode where I can use 87 octane gas.

It sounds like you are just looking for just performance? Here is a link to a tuner that is highly respected and has reasonable prices and from what I hear great service.
