I went to tune time performance for a tune and tune pac 2 install. Met some really cool people there. Matt and mike and a few others. I have a 2007 2wd with the e-fan, CAI, 160 stat,wester tune and 40 series flowmaster with res delete, My numbers on the mustang dyno with all the mods are 301hp and 314tq. I thought that this is a little low. Matt said that the 07's have a learning curve and that they improve over time as the ecm relearns. Your thoughts on this would be nice. I know dyno jet numbers are 15% higher then mustang numbers. Am I where I should be with these mods? The iat Temp were around 110 degree

All of them have a learning curve, but I would think your numbers would be higher as mine were 322hp and 326tq stock on a Mustang Dyno in 95 degree weather.
My Wester's tune has been fine, 13.521 best with tune only, but she does run a little fat. I have pulled several 13.0 and 1 12.98 with efans and UD pulley. I'm good for 13.3s at anytime.

do you think that it could be the flowmaster exhaust? cause the baseline was around 286hp and 290ish tq with the flowmaster already installed

Just go to show that Silver is the slowest color.

take the flowmaster off

:iamwithstupid:

You would be better off with the stock muffler over the Flowmaster or go with a free-flow design aftermarket like magnaflow

This is not the first time I have heard that the Flowmaster is the wrong choice for these.

So the corsa sport CB would give me better results then that flowmaster setup. Can the flowmaster bring down the dyno reading that much? I'm concerned because on the tune time performance website. they state that a tune pac 2 would net 39hp and 48tq. I'm not even close to that. My baseline with the flowmaster on a mustang dyno was 284 hp and 292tq. do the math and that's not even close. what should I do. 1500 is a lot for 17hp and 22tq gain.
