You wont see full boost till 4k rpms or more. Considering our redline is at like 5.5k or so, thats a pretty crappy power band. I would take that turbo, sell it, and buy a t3/t4. A t3/t4 50 trim .63 ar is perfect for your power goals, with room to grow. This t3/t4 is really the best all around turbo for our engines. If your certain you only want below 300, a gt32 will give you that at a faster spool than the t3/t4. It also is a great turbo for our engines.
At 10 pounds of boost on that t40e you would push past 300 hp with no problem. Anything under 300 hp and that turbo would be grossly inefficient.
For your goals, you need a smaller turbo.
