Dumb question - so the gains you saw today were for the no-tune version of the PMAS intake. The tune you're running was for the flex fuel and the stock intake?
I would recommend Globex Performance:

They mainly work on Jeeps, but the owner has a Mustang so they work on them too. They do amazing work with gears.
The FRPP track springs and shocks are very well matched and helped resolve the "floaty" feel of the stock PP suspension, without being harsh. I guess if you prefer linear springs (the FRPP springs are progressive) you would go with BMR, I believe several members here are very happy with that setup.
No rubbing here.
Mine is lowered on the FRPP Track Pack springs and I'm running 285/35/20 up front and 315/35/20 in the back. My regret is that I didn't lower it sooner. I too was afraid my tires might rub, and I kept putting it off for months. Now my stang rides better, handles better, and...

Kinda agree here. I debated for weeks whether to get the Hurst or MGW for my '08 GT. I originally went with the Hurst. It rattled and felt poorly made. After a week of driving with it, I ordered the MGW and gave the Hurst away to my mechanic.
