After cool down it made 373/357 BTW 1:1 is still a 4th gear pull, tried 5th and thats a no go, speed limiter is at 141.

Letting it cool down a bit then will make another pull. I would say the catback is good for 10rwhp across the board. Might put a intake on in a bit.
**Catback stick car, with the top down lol**:thumbsup: BTW this is uncorrected HP
67 to 73 uncorrected sounds like the cat back is good for 5 to 10 rwhp. Was this the same car with catback or a different car with cat and no baseline? Still not enough info to start making general comments on mods I believe.
How will 1.32:1 effect dyno numbers?:shrug:
4th is not 1:1
5.0 gt ratios are:
1st 3.66:1
2nd 2.43:1
3rd 1.69:1
4th 1.32:1
5th 1.00:1
6th 0.65:1

Just for those wondering 5.0 mustang magazine just did a dyno of the 2011 and wanted to test the argument about which gear to dyno in, well
4th gear produced 381.84 hp & 342.09 tq while
5th gear produced 366.75 hp and 335.96 tq meaning the car lost hp and tq in 5th compared to the 4th gear pull
5th gear produced 366.75 hp and 335.96 tq

The funny thing is the a/f stayed at 14.6 until the very top of the run on the first 2 pulls. The second 2 pulls the a/f looked good right under 13. I will get the pics and graphs up later.
