Next Step
I do like the intercooler upgrade with piping. The stock one is pretty pour. I don't know about everyone else, but when its in the 90's in Colorado, it felt like driving a non-turbo car with the stock intercooler.

Yes well the altitude contributes to that also...many choose not to upgrade their intercoolers due simply to the weight difference. Most if not all aftermarket intercoolers are heavier than stock and add weight in the worst possible part of the car (besides the top). Just something to think about if you autoX or road-race
The EVO9 is pretty darn good right out of the box. Once the exhaust is opened up you can max out the injectors and turbo without needing cams.
The biggest bang for buck mod you can do now is an octane and boost increase. Either run race gas or install meth/alchy. This should add 40whp to your current tune. Thats the easiest way to make power.
If you want to go about it the hard way then opt for a better FMIC and LICP. You may want to consider going back to the stock air box as well. Sucking in hot engine bay temps only adds to intercooler heat soak and higher IATs.
As for the cams and 20G..... on average cams don't add much power unless you are really working the stock turbo hard or you have an upgrade like the 20G. Most people see about 10whp which is very little gain for such a large expense. I would do a 20G prior to cams. At higher boost levels the 20G on stock cams is good for 25whp. To see nice gains from either mod requires more airflow and boost.... thus the suggestion for more octane first.
For the record most 20G cammed EVO9s are at about 380whp. It is also interesting to see a good majority of those give up some torque for that added horsepower.
Do a search for username RAZORLAB. He's always posting excellent mustang dyno graphs of EVOs in various stages of mods. His results are consistant with others on this forum.
