This is a great thread with lots of graphs. I found a few that look a lot like mine. None make as much low end torque as mine. I did find some s52 with M50 intake reviews of the epic tune and they said the samething. HUGE noticeable gains in low end torque. Up top felt the same. Perfect then for the street since I am very rarely in the 5500rpm+ range

Ok so when I put my itbs on I popped the valve cover off. I have an s52 with s52 cams. The cams are installed with less overlap. Giving me more low end torque. Losing a little hp up top. My vanos needs to be shut off earlier to compensate for this. My off the shelf tune is obviously not for this setup .will be tuned on megasquirt April 23rd

Most of the people who have low/less torque are because they aren't tuned or are running crazy/silly exhausts.E92 Msport

You either want to do it right, or you don't, its entirely possible to make the same or more torque you have down low and more power up top

Yes. My outerwear filters we're not flowing enough air. Their was a vacuum at 4k. I got some pipercross and itg's coming in the mail. Then have to make an appointment to have retuned :( pain in the ass. Live and learn I guess. I thought the outerwear filters wouldn't be restrictive. Didn't do my homework on them.
