Also, no one with comptech headers were able to put out the same gains comptech's dyno showed.

No one? I went from 190 stock to 223 with the Icebox and Comptech headers

pretty much all the header dynos i have seen on here showed a 17-22hp gain. now there are one or two people who have claimed 25-30whp, but i never personally talked with them to ask about their mods or to see their dyno sheets.
that 12-15 at the flywheel estimation is a typo in my opinion, or a miscommunication if someone said it on the phone. i've never seen a header give 8-10 at the wheels. that would be a complete waste of time and money IMO.

but it isn't really that bad.
i expected to hear more noise.
they OEM are cast iron...for quietness amd smoothness.
we put thin walled stainles tubing inplace of thick cast iron.
u gotta expect some noise.
i doubt that the comptechs are as quiet as the OEM iron manifolds.
right?.

260hp - 25% = 195whp
Once supercharged the car made 295whp which is the highest a 5AT has every dyno'd with the Comptech supercharger so it isn't like my car was just weak from the factory.
All dyno pulls were done at the same shop on the same dyno

what other mods did you have on when you did the s/c? i'm assuming you used a high boost pulley? how was driveability on the car at that power level?
i just think the numbers are off somewhere on the dyno. i remember when i ran my dyno the guy running it said the mustang dyno's read low. i believe my exact number was 198 (i have to go back and look through my old post) but he surmised it should be around 201 or so.

Drives great. My new CL-S makes over 300whp on stock exhaust.
