First dyno run

Hi folks,
First dyno runs for my new purchase is copied below. I'm new to these, so any insights would be appreciated!
The guys didn't have the manual for the boost controller (Gizzmo MS-IBC), and its settings were all over the place.
So I think they ran it on about 6 psi and then 10? Have got the manual now.
Sketchy fan/controller on the intercooler didn't warrant anything high either just yet. Plenty still to do obviously!
 
Some pics of the car here: http://www.mr2australia.com/mr2play/photo.aspx?albumid=30&apage=1&asort=1
She's got a gen II 3SGTE (rebuilt about 5k ago) stock ceramic CT26, aftermarket intercooler (unknown brand), weird custom exhaust (commodore??), unknown BOV, unknown filter, stock ECU.
 
Any ideas, info or suggestions welcome. I'm hoping to gradually get it to a "soft/medium-core" track machine, hopefully around 250 - 275rwhp, for now I'd settle for 200!

    looks like an ebay intercooler, you will need to have a decent fan on it and also get a fan shroud made up for it, have a search on here and see what others have done.
    inlet temkps are what will kill the power and without a decent fan on that cooler your not going to get anywhere soon.
    the bov looks like a HKS one or a knock off HKS one.
    filter also looks like a HKS one.
    the stock ct26 will run out of puff higher in the rev range so might want to upgrade that if you need that 200 odd kw

    that seems to be boost set to 10psi? with a bit of a spike as it goes up, or maybe set to 12-13 and a slight drop as your air use goes up... either way not bad. You could try playing with your boost controller to get it to target a bit higher if you wanted, but what you'll see is more mid range power and a boost drop as you get higher in the rev range and the turbo cant flow enough air to keep up the pressure... so you wont get a huge gain in your peak power.
     
    I wouldn't get too hooked up on your boost for now. try tidying up other stuff like shrouding the intercooler and getting a fan on it and maybe shrouding the inlet pod or moving it closer to the air duct on the side of the car to get nice cold air. You'd be VERY surprised with the difference cold air can make to power on these cars. I remember reading somewhere that 20 deg farenheit difference in air temp made 30hp difference to a car in the 200-220hp range. (thats about 22kw for 10 degrees celcius) to make matters worse, as your temps change your engine will also start to pull timing, so you get even more of a drop off in power... and if your pod and your intercooler aren't making the most of fresh air then those temps can go up FAST.
     
     
    and the best part is it's free power... cause typically your car wont lean out its fuel when you run hot, so you use just as much to go slower.

    I would suggest do upgrades in the intake & exhaust order,
     
    Get a decent pod filter & buy a heat sheild or make one from sheet metal,
     
    For a very noticable gain get the 3" dump pipe fitted as the stock cats are restricive and now over 20 years old so probly full of crap, and get a nice  2.5" to 3" exhaust.
     
    Combined with the suggested fan upgrade on your intercooler and you should see atleast 200rwhp.

    You're on the money there 3sgeTurbo:
    Intake, dump and exhaust all  done, with the hi-flow ct26 it's hitting 240ish hp, limit now being fueling. See http://www.mr2australia.com/mr2play/tm.aspx?&m=76740&mpage=3
