Mileage

How much do you think having a bunch of miles on our car affects our hp output or does it at all? just curious, kind of a dumb question.

There are a lot variables that go into the question i suppose. For instance, my car is stock with a 135K on the clock and it runs like a mother fucker, but then again I have never driven in one with less. I suppose as long as it well kept it shouldn't be affected much but it inevitably will. Most likely due to ring seal issues and compression leaks, but that just has to due with the nature of the moving parts. You can upkeep the best you can but the fact is metal rings going up and down a cylinder millions of time will start to wear. I would think that that would be the only factor assuming the car was kept up very well. Anything else that would rob power, like a dirty tb, could be reversed easily. Am I missing anything?

Pretty much what he said. Leaks, clogs, holes, tears, etc. On a side note, the LS1 engine is one of the best ever built. It can take a beating...

i say if it has alot of miles but its been takin care of, it wont matter too too much, BUT every car is different, but obviously if the cars been beat on and has alot of miles, then it will affect it alot

alright good, i was just wondering about it. it may have affected my driving a little bit.

if you want to know for sure do a compression test on your cylinder and make sure they maintain a good pressure and that they are with in tolerance, really the only way to know

Nice run, thats a great time even with a brand new car. It really shows how well built these motors are and how they withstand the test of time.

Howmuch did you gain from the tune? do you know what you were at before the cat-back?
