Is the upper IC pipe really worth upgrading?? I've replaced the stock BOV with a 1st gen BOV. If i replace the stock IC pipe with an aftermarket one will I feel a difference in power??

A mesic brother did a test a little while back at the track. He said after he istalled his IC pipehe dropped .5 in his ET in the 1/4 mile. I'm not sure what dif that made in the MPH. That was on a stock setup.
I noticed there was alot more response from Sheila when I did mine.
You should feel a big difference. It you have retained stock i/c piping you will notice that left of your BOV the i/c pipe is quite restrictive. You can get the pipes real cheap if you look around, I got the GReddy pipes used from thepartstrader.com for $85 US and they were in perfect shape. Unfortunately I did that and BOV mod at the sametime so I can't quantify the how much power was obtained from either seperately. But now I hold 18 psi on a T25 with no boost controller!
