E55 Long Tube Headers - $1999!!!
Just bolting the headers on with no additional tuning yielded over 30whp/30wtrq on our dyno dynamics dyno.
I will ask the customer to post his feedback and dyno graph. He has the Eurocharged 172mm pulley, Eurocharged HE, CM30, Eurocharged LT's, and LET Tuning.
We have another LT customer / forum member who lives in NJ and he was able to run the following time with the headers installed.

Do you also have a upgraded throttle body or still using the stock one. I would assume that since you have all the other mods it would be most likely a modified one. Good luck on your quest for 10's because .4 is still a long ways away, trust me I know...
.How does your HSTC like daily driving? I hear good and bad, some say it always feels like you tranny is slipping and other say it drives like stock.
