power loss...maybe?

it really could be in my head.. maybe im not use to the sound or feel of the H pipe since i just got it today. it sounds great. but i cant help but feel like its going slower than usual.
is there anything that i might need to do like get my car re-tuned to fix something like the air flow to fuel ratio?
my friend also said "remove positive battery cable, touch it to the positive battery post and then put about 40 miles on ur car and it will reset stock comp and tranny computer" & "maybe ur computers use to a certain way of driving so u have to reset it or give it 120 miles worth of driving"

thoughts, suggestions?
thanks

your car is too old to be a learning computer. the tcm and pcm are set parameters. disconnecting the battery wont do anything for you. you probably just need a slight adjustment on the tune. or like you said. its in your head. the newer vehicles have to learn to shift again if the tcm is reset.

I dont know for sure, as i havent done this yet, but it could be a loss of backpressure causing you to lose some low end torque

hey no problem. i was just sharing info. its a myth that everyone listens to but does not research. just think. the more exhaust you get out of the cylinder. the more fresh fuel and air you can get in.

I think your just use to the sound of the before and now that you have the after on your heard is thinking of how your exhaust should sound at your shift points. I say it's all in your head
