Baselined my Z28
Personally, I would dump that Flowmaster - do a search and you'll see why.
.....it's pretty restrictive comparitively speaking.
Also, although being a "fad", I would look into gettin another TB with a screen (just my opinion). Even though you gain a few HP the potential for damage carries more weight in my book.
Not to totally negitive, those are good numbers and you have the potential for more !
