That's right. I didn't get anything I could feel with the Borla's. I know
Kenne Bell told me they were only able to squeeze out 7-10 HP with theirs.
They had dyno sheets to show it but wanted $700 for a set. My Borla's cost me
$390 shipping was free. They were a pain for my muffler man to put on. He had
to cut the y-pipe to make them fit. The Jet Stage I chip is the exact same
part no. for the 5.2, 5.9, and the 4.7. I tried one and got nothing from it.
Maybe the Stage II is different who knows. In my personal opinion I would
stay away from both of these mods. for the 4.7. Save your money.
