Ok here's my input being my bread and butter is the stock turbo/big wheel type deals.

1. I would ditch the map clamp and get a NEO/Dtec with a return line. This alone will give much better timing, better fuel atomization, and makes tuning 100% easier. The spike and fall in the fuel curve is killing the top end power.

2. Stock intercooler has made near 300 before, if you were 290 range I would say the FMIC would help you get over 300 but not 33 HP. The flow of it is decent, it's the cooling properties that suck when you get tremendous EGT's from pushing the hell out of that turbo unit.

3. Stock airbox with the bigger wheel demanding more airflow is definately making a difference in the amount of power you are making. I would get an AGP or equivilant cold air, and hit the dyno again.

Puzzling that with water/meth your intake temps are so high. I would check the turbo to make sure the shaft play isnt there, and that the turbo is sound.

Also make sure you do the normal things, boost leak the car. Im not talking about a boost leak test up to 10 PSI and calling it good. I want you to crank it up and check for leaks 5 PSI at a time until the tester blows off. Yeah it can seem scary but it's a sound, it wont hurt you. A true boost leak test will hit 20+ PSI and show a SHIT TON of stuff you wouldnt see before. If you dont do it this way you might as well put your mouth on it and hope that it shows something.

If you're going to do 5 minutes between runs you better have you and a friend with full bottles of water spraying all the piping, FMIC, and other heated objects down. It just isnt enough time as Jay said, and you wont see efficient pass to pass numbers. Figure if you were on the street you would have MUCH better cooling on the intercooler, and you wont see the same characteristics on the dyno unless you take the necessary means to get it that way.

Check the turbo, that would be the first problem I'd look for. The V2's are better, I just installed one and had much better results. If it's not the turbo then you have the power there you just need to find it. Boost leaks, better tuning equipment, and just a little TLC. Stock turbos and big wheels are a bit tougher to get the power from vs a big turbo. It takes finesse. If your turbo is sound then just spend some time on it. You will be impressed with how easily 50 HP can come if you just play with it a bit.
