How much power is a PCM for less tune on a stock LS1 automatic car?

I have a 2001 Pontiac Trans am automatic car. I ran the car at the local 1/4 mile drag strip last week and made two passes. My best time was a 13.5 at 103 mph on steet tires. My car is bone stock with no exhaust or anything. I would like to know how much power I would get if I got a PCM for less tune.

Not a lot. I wouldn't waste my money on a tune until I got some other Mods done.

If your stock if you need to get a Lid. And think about exhaust.

another vote for ... dont waste the money. get the bolt on's done

What they said.

Don't waste your money on a tune for a stock vehicle, get some mods first, then tune.

ya regardless of how much you'd "want" to keep it stock, after you find a small HP increase, you keep coming back for more...
