Glad you got a before dyno, that will be real handy once you install the TS2 kit.
I'd strongly recommed you pick up a copy of Renovelo's bytelogger. I'd love to see a datalog on your car before and after the TS2 install too. And, its very useful for making sure the tune from ESS is all on par. I've got a transfer function that converts your pre-cat O2 voltages to an AFR reading, so you'll know if you're running good or not before and after.
I bet your dinan TB might demand a few tweaks possibly?
Are you running without any tune at all now? You must be getting the SES light for the SAP and headers.
Don't forget to tell the ESS guys to turn off the SAP too, they can do that now ;)
