Default Need info and recommendations

I have 06 wrx with Cobb catback. accessport and perrin pulley. I want to get the cobb dp later this year as well. Have a few questions.
1.Would you recommend me upgrading my fuel pump at the same time?(I plan on getting new turbo in future anyways).
2.Should I get a boost controller. If so what do you recommend
3.Should I get a new heat shield or just cut out the oem one?(I plan on getting FMIC, so if its not needed then I can save some money and not buy a new one)

I do know I need to be careful, I will be upgrading to PPG gears next year. Any other recommendation would be great, Thanks

1. fuel pump doesnt hurt anything so the sooner the better.
2. you dont need a boost controller unless you want to go over 20psi
3. up to you. You can use both if you want.

1.Would you recommend me upgrading my fuel pump at the same time?(I plan on getting new turbo in future anyways). Not Necessary unless you choose a different turbo path.
2.Should I get a boost controller. If so what do you recommend? No, The AccessPort already has the mapping specific for the Down pipe which will put you at stage 2. If you want better boost control get a 3 port Electronic boost control solenoid from GM or Prodrive. People that get the MBC tend to want to up the boost and lean out their AFR's and then Knock occurs and then engine problems. and Get a protune for the ebcs.
3.Should I get a new heat shield or just cut out the oem one?(I plan on getting FMIC, so if its not needed then I can save some money and not buy a new one) Trim the Stock Heatshield for now.

I do know I need to be careful, I will be upgrading to PPG gears next year. Any other recommendation would be great, Thanks. Find what is cheaper, PPG's or a 2007-2008 STi Transmission swap. The 6 speed is Super nice and VERY strong.
answers are in red^^^^

For future turbo path. On the 2.5L I wouldn't recommend anything smaller than the 20G and nothing bigger than the GT3076R unless you plan on doing internals and head work. I chose the Blouch Dominator 3.0R which is the bolt on version of the GT3076R. I spool up 200 rpm later than I did stage 2 (I am an STi) You will spool slower than your stage 2 because your stock turbo is tiny. Needless to say, it spool quick and makes great consistant power. Best bolt on, Rotated will always be better though.

1. Get the Fuel Pump done to get it out of the way.
2. For Boost Controllers many like the aftermarket EBCS(There are many) and some use MBC. It's your choice but both will require tunes. You can still just use the stock one too.
3. Save money and cut the stock heat shield. No need to waste money on a new one if you still have your old one.

Careful when choosing Gears. Make sure you know what kind of ratio you want as Autocrossing, drifting, or drag racing you want a good gear ratio. I drag and I hate my 06STi Gear Ratio's.
