Many ppl at stage 2 go with a fuel pump for a piece of mind. However, it's not a must have at all. especially since you have a newer 4th gen.
You dont really need the ebcs either.
If you could find a good deal on the tmic, your car will benefit from that a bit. Otherwise, most ppl dont touch their tmic's at stage 2.
Why would you replace the up pipe? 07-09 were catless.... So no benefit in replacing the up whatsoever.
In an 08, all you really need is a downpipe, and a tune. Personally, i would take the other money you have set aside for your up, ebcs, etc... and get endlinks and sway bars, so you can control your new found HP a bit more.
