N-E 1 notice a difference in HP between Borla Plates (10+psi)

Guys,
I was doing a search and came up with this link:

http://web.camaross.com/forums/showthread.php?threadid=39005&referrerid=19123

I wanted to know if any of you guys running 10 psi of boost or more (400RWHP or more) noticed any HP difference at the Dyno or Track with your Borla Wide Open.

My exhaust system currently consists of
Grotyohanns LT, 3inch Y Pipe with dual Random Cats and Open Borla (See sig for rest of mods). My Borla is a lil too loud (No Plate) for every day usage (I drive 600 Miles Weekly) and I wanted to order the E-Valve to quiet down the car and only open it on demand when I needed or wanted it but after reading the link above, I am not sure the E-Valve is worth the money. Please let me know your experience in HP numbers, Boost numbers and A/F ratios with the Borla Opened and Closed.

Will the motor breathe that much better with the Borla Open as opposed to closed?

All Help is greatly appreciated.
Claude

a friend of mine has a T/A(ls1 though) and i watched him put down 541 with plate closed and 547 with it wide open. i dont remember the torque differences though.

so he only picked up 6 rwhp with it open. not worth it for all the noise!

Thanks for the input broh...
What kinda of set up was your friend running? Motor/Boost..etc??

Just out of curiousity, was that 6HP all the way thru the RPMS or just peak.

Thanks again,
