A tune does virtually nothing on a stock (gasoline non-pressurized) engine and is a waste of money.

You first have to drastically increase the air flow in and out - then a tune can have a real effect. With stock intake and exhaust a tune is incapable of making any real gains other than increase pollution.

I spent 40 years as a machinist and back in the mid to late 70's, when the first NC machines made their way into shops, I wanted to learn. I had plenty of experience on manual mills, lathes, grinders and tape machine but I was young and eager to learn the new technology. My foreman told me that computers were just a fad and I would be foolish to learn them. He was old school, stubborn and couldn't accept that things were about to change. He really didn't do his research, did he? (whispers) Carl??? Is this you?


FYI.... I added a cold air intake (CAI) and a cat-back system (dual exhaust) with 40 series Flowmaster mufflers a year ago. Regardless, a custom tune will improve a brand new, factory fresh vehicle over the "canned" tune (one size fits all). Better throttle response, better MPG, better fuel management, crisper shifts, more HP, more torque and a long list of non-performance related items that annoy some people.
