It is PLENTY streetable however get used to lag. If you dont mind it go for it. Me and Nate from DSMotorsports have made a good thread about the lag of different turbos using logs from plenty of different Evos with different turbos which show true spoolup... not word of mouth crap. I drive mine daily and dont see any reason anyone couldnt. The only thing is get used to no autocrossing or any quick spool type stuff like that.

The stock maf is still working for me and at lower boost (26-27) the car traps at 123.5. I have ran the turbo at 30psi but my clutch started to fail but the maf was still reading the air correctly.

I will also be trying out a GM MAF with a DSM Translater and use the Utec to scale the airflow down or up to where it should be (The injector compensation thing in the Utec should work for this) and once it is close I will fine tune it just like the stock MAF. Once I get some time to drop the clutch in I will try out the GM maf and post up my results.

It caught turbulence and always made my car misfire at Interstate speeds at part throttle. MAP is a beautiful thing. Car runs almost as good as stock. I just need to tweak my cold start a bit, but it is no worse than my car was on the stock ecu with my mods (cold start that is). Everything else including part throttle let off and cruising is way better. You might be able to control this with the Utec too I dunno? I say get away from that MAF sensor though. The trick is to have a buddy that runs a 10 second talon help you tune your car and then learn off of that My car has one day of tuning in it. We will see this weekend how it runs. It felt pretty damn good at 25psi and only 10 degrees of timing though. That produced almost 0 knock on 110 octane. Will be running 116 this weekend with 2 more degree of timing.

Aside from cold start, drivability, etc.. Many of us have to contend with OBD-II and Emission inspections..
