intercooler is a good place to start. Thanks for the timely move, Jamie.

Intercooler, as allready mentioned
increasing boost, bleedvalve, better would be a boostcontroller
Don't know where the USDM LegT got it's Fuelcut. It shouldn't be any problem increasing boost to this point manually.

Fuel cut is 12.5, and you definitely don't want to go there unless you've intercooled it. After that, you can go a little bit higher if you make a VRG FCD as laid out on Legacy Central (which for some reason is down today).

After that, a bigger turbo comes into play. TDO5 and v8/12 takeoffs are the most common approach. If you can get a TD05 and intercooler at the same time, it's a good approach...
