Thanks, man! Yeah, I think it might be time to start running some tests before going any deeper into mods.

I agree. No point in spending a ton of money for more power/torque if something seems wrong and you haven't figured out what it is yet.

Well, maybe I'm getting desperate, but I popped off the highflow cats today and installed the off road pipes. I'll wait until I get the fuel jets for the nitrous and then I'll get it back to the dyno and see if it gained at all.

cats are known to rob some power but i dont think they are steeling quite that much...i think a leak down test is a must..Good luck on your case of the missing tq

Yeah, I'll probably run the tests this week. I'm guessing that the cats will be worth 8-10.

Also, I ordered my bottle heater and different fuel jets so I can get it back on the dyno for fine tuning once those come in.

Taking the high flow cats off ended up being worth 8 rwhp and 12 rwtq.

The final numbers on the car were 432/386 with the cutout open.

I ran it at the track last night on motor and it trapped a consistent 3-4 mph than before the heads, rockers, and cat removal so the power is all there.

Figured you guys would be interested in the real world results to back up the dyno gains.
