With a high flow panel filter, dump and exhaust, I was making 166kW atw. Pod filter won't make much difference on standard ECU and suction pipe, so you'd be about there. Not sure if the intercooler will make any difference in these?
After I did all that, I was also making 15PSI. If yours is a 250t RS Four (which is what I've got), I think you're at 12PSI stock, and if you've got a decent dump and exhaust you'd probably be making 14-15PSI.
I'm leaving mine at 15 until I'm ready to upgrade the turbo. Scotty has run his on a standard turbo at 20PSI.
There are a lot of other mods you can make, depends on what you want to do, what you want out of the car, and how much money you've got. Do a search and you'll find a lot of info.
