That turbo won't even wake up until you hit around 15+ PSI. Wink

For what it's worth, when I still had the stock turbo on my car (no upgrade, chipped impeller blades, and lots of shaft play), I made 289rwhp, 295ft lbs tq @ 15psi.

Now, considering you made nearly 300rwhp at 11psi, I'd say you're doing just fine. It will blow your mind when you reach, say, 18psi on that turbo. You should be around 400rwhp.

Take baby steps, though, otherwise you're likely to lose control. Wink

Edit: I also forgot to add that I also dyno'd on a Mustang. (Which everyone says they read low/more accurate compared to a DynoJet)

Had you done it on a DynoJet, your numbers would both be higher. I prefer Mustang Dyno's.

kool evrything is going as planned ill post my tune and maybe you can help with a higher boost tune but i dont want too go any higher then 15 psi till i get some arp studs.
also the guy was boosting it late full boost at 5500 rpm as when i boost i can hit full boost at 4000 rpm would this not also affect my numbers.

It would certainly effect your numbers. Keep in mind, also, that sometimes it's difficult to get the car to boost as early as it should when it's on the dyno- It's hard to get enough load on the tires to simulate the road. Wink

Honestly, your best bet would be to slowly increase boost, and datalog what's going on with your laptop. Then, you can tune the car sitting still, rather than tune-on-the-fly.

Keep an eye on the AFR's, and make sure you're not going lean.

Every car is different. Even if I had the exact same setup as you, chances are very very high that my settings wouldn't be the same as yours. Wink

Most of those numbers are practically worthless without a log to look at.

Shaeff's right too, can't just copy someone else's settings.
