i have an 04 cav 2.2 ecotec L61 5speed.. i have a cold air and an exhaust on it.

i was wonder what i would look to gain by retuning my computer, my friend has an HP Tuner and said hed do it but he would need $100 to unlock my computer.. just wondering if its worth it or if its even going to make much of a difference.

I know someone who got 8whp on a bone stock Eco. To me that is well worth the $100.

Will it make an improvement? I don't see why not.

And you'll gain gas mileage if he knows what he's doing. I get better mileage with the blower on than I did stock and I'm betting thats almost all tune.

The way I see it a stock tune is set to adhere to certain pollution limits and mileage...etc. So yes a tune will help along with the intake and exhaust.
