I've only been on a stock header, I'll be getting tuned again soon on the JDL UEL.

I'm on a different setup now, but I hit 330whp Mustang / 385whp Dynojet with 15.5 psi and e60 and a stock header.

^ wow who tuned that? very impressive on a stock header

This should be in the FI section

and you do have a dynograph to show how broad the power band is?

Well, we're on the ACE now. We've tried quite a few others.

what are the primary,Secondary and collector sizes on that header?

Delicious Tuning, Infamous Performance dyno, which they say reads ~17% lower than another local, popular Dynojet. Also, it says E85 but my flex fuel kit was reading 62. Definitely felt stronger once I was reading 85 every time thereafter.

My current setup:

Jackson Racing Supercharger(stock pulley)
JDL UEL Header
PLM overpipe
HKS Dual front pipe
HKS Hi-Power 3" Exhaust.

e85 Dyno tuned by Mike at Moto-East on a dynojet.

How many miles do you have on this setup? That's really pushing the stock motor. I'm on the 210 blower and really considering the 335. Did you upgrade injectors? Stock transmission?

not really pushing the motor we tuned some tq out through cam overlap on the 80mil and e85-e98 it thrives
stock trans injectors are DW 550

42.7mm, 50.8mm, 63mm
