Re: dyno chart.......is it good....help. (dc2greddy)
Your gonna need to give a little bit more info than just that. If its a ls @ 7psi on a straight t3 I would say its not bad. A gsr @ 7 psi on a 35r better be quite different.......get my drift??
What motor, what turbo, what manifold, what exhaust, compression ratio.....etc.
Just from a quick look I'd say your runnin a bit lean. Would b a good idea to richen it up ~.5 pt or so. I'd also guess its a vtec engine with crossover set to ~5300rpm....needs a bit of fuel there as well. I'm no pro tuner, this is just what I see at first glance. Give us more info.........

you don't need an adjustable fpr unless your injectors are aready maxed out. just add more fuel using crome.

You don't need any type of FPR. Your a/f's look about .4-.6 leaner than what I typically shoot for. Changing your base fuel pressure will off course throw off your entire tune... so add about 4%-6% fuel under load opposed to dicking with playing with a FPR. Going richer will also kill a little power... but it will keep your engine safer.

Re: (dc2greddy)
Upsize everything starting from the turbine outlet (elbow/downpipe, exhaust, muffler, whatever). If you want a nice flat torque curve, best to go with 3" everything.

My numbers are in my sig...
boosting 8 spiking to 13... i dunno wtf is up witht he huge spike.
Stock greddy downpipe with a 2.25 inch shity catback.
Soon ima upgrade to 3" exhaust and should be good for close to 300.
edit: also, finding an elbow to fit it is really hard. I dont know of any company that makes them, so it would have to be custom, and it would probably cause oproblems when trying to keep ps and ac... If you get the downpipe and exhaust, you should get close to your goals.

Like I said.. nobody makes an elbow for it, so it would have ot be custom.
The elbow wouldnt hurt or help it that much, so just upgrading the downpipe and exhaust would be enough to get you in the 300's or so. If you want much more hp than that, you really need a new turbo.. I'm building my engine and going to upgrade to a gt30.

well think about it this way... what kind of power are you making stock at the wheels?? 140-150ish?? 65-75 hp from 7 psi isn't that bad.. get a larger downpipe and you will see another 10-15 whp..
