So what sort of power gain will I get with a front mount twin 2 & 1/2" mandrel bent system from cat back and Pod, if the boost was pumped up to 13 psi.

Trent, please don't be lazy and get us to do all the work for you. There has been a lot written about upgrades for the TT, use Search and start reading. You might enjoy it and learn a lot at the same time.

Well Here are my mods.....
FMIC, STandard Dump Pipe, 3 inch Down pipe into 3inch Cat, Spitting into Twin 2.25 cannons. BFI air box with K&N Panel filter running just under 13psi...
Red lines running low setting round 11psi, Blue lines running High setting just under 13psi.
Oh, thats around 242 HP at the wheels(roughly 250kw at the motor?) Hope this helps you a little.

Mine totally stock - 166rwhp (rear wheel hp)
+ cat back, BFI (K+N filter) and 12psi - 217rwhp
+ dumps and front mount, 14psi - 236.6rwhp
+ S-AFC - 302.0rwhp
an extra 65.4 hp from your safc? is that normal when i got mine tuned (x-speed) i only got an extra 18hp. similar mods too (fmic, downpipe+exhuast, pod filter, bov)
Even after getting it tuned im still getting a build up of carbon all over the back of the car. Im starting to suspect that maybe my o2 sensor is rooted. I'm thinking next time i change my oil i should probably replace the o2, clean the insides somehow and look at getting it retuned. Damn its annoying though, was pretty pointless getting it tuned in the first place if this is the case, not to mention a waste of $$.

Always good to change your Plugs prior to a tune if they have a few KM's on them. ( Maybe when Paul had his dynoed prior to the SAFC install, his plugs coulda been slightyl fouled?) WHen i had my car dynoed, i only changed the plugs the week beforehand. ( Thanks Mum and Dad for brand new Iridiums for my Bday at the time,hehe) And im so glad, as the ones i pulled out...... Looked like they were in their for a Looooooooooooong time.

this is my dyno read out. 237hp before (red line) to 255hp after (blue line). I didnt actually get to see the guys who did it personally, but is there anyway to tell if my o2 sensor needs to be replaced by looking at the read out. I also have had problems in the past with the car running pretty rough some mornings when i first start it up.

Daniel, do you have dumps? Dumps and downpipe aren't the same thing, dumps replace the y-piece in between the exhaust housings of the turbos. It looks like you have a restriction in the top end.
Maurice is right, my AFR's were far worse than yours before the tune. They were sub 10:1 from about 3500rpm onwards.
