They claim a whopping 3.3 hp @ 4800 rpm for the FIPK for the 3zve....

Which begs the question how effective the ISR mod is ? Essentially, the critical portions are the same... you end up with a 3" ID tube with a smooth bend replacing the ugly tube/maze/tube affair.

Other than seat of pants, anyone dyno an ISR mod on a 2nd gen ??? Pretty unlikely I know as if you only drop $30 or so on parts, you don't want to blow 5 times that ona dyno run

3.3HPs @ 4800 rpm? RPMs that high for too long and here comes the A/T Temp Light...

I dropped $30 for my ISR mod. Not for performance, but because it looks so, so much better than stock. However, I too am interested if this mod did increase performance.
