You don't need your ECU chipped/re-tuned if you increase the boost, it already knows how much fuel to put in. The only time you would need to re-do the fuel map is if you tried running boost beyond what the map caters for, but in most cases the upper limit of boost/load on the map is around where the injectors upper limit is anyway.

Chip your ECU if you want to alter the ignition timing, alter the A/F ratios (you can lean them out considerably by split-railing the fuel lines), upping the boost without a EBC, or removing cuts. I would get a boost controller and try upping the boost - if its beyond what the ECU can handle then it will let you know.

Sure, but i think the best way would be to run a chip. You'll get better boost response, better economy (not always) and most importantly the removal of your boost and speed cuts, no point in raising the boost if you hit the limiter.

What turbo are you running? you might have picked up a Psi or so with the exhaust and intake, are you running a highflowed dump pipe?

The best way to increase boost is with a chip, as the chip changes the Air and Fuel to match the increased boost.

You get what you pay for, I mean how much info can you get about the map on it?

Have they tested it on similar vehicles? whats the AFR under power, wastegate spring psi etc

16psi is the limit, but you could run an inline restriction to taper it off.

380s will be good for around 180kw at the wheels after that 440cc yellow tops from V3/4 STI and you'll crack 200kw@wheels.

Then you'll have to go aftermarket and require a Tunable ECU.

[Heat Wrapping Downpipes YES/NO?]

Go for it then, every little bit counts.

[Heat Wrapping Downpipes YES/NO?]

You've gone single on your GTB? try and fit the clam shell heat shield over your heat wrapped down pipe that would be best, rather that just heat wrapping it.

If you still have the twin setup then just leave it.

[Heat Wrapping Downpipes YES/NO?]

He's right but as i said you should be safe with your downpipe. Headers you probably would be best to get them HPC coated.

[Heat Wrapping Downpipes YES/NO?]

You shouldn't get water on a downpipe but it's known that heat wrapped exhaust components will rust faster that if they weren't.

[Heat Wrapping Downpipes YES/NO?]

Another point, have seen a few speedo cable on early RS and WRX eventually harden and seize the cable due to heat from the downpipe (not to mention my own)
