This is due to a maxed out 60mm turbine wheel. With the release of efr7670, garrett put together the gtx3576. Not a lot of data out there on this turbo. I've talked to a few guys that have switched over from a gtx3076 to the 3576 and they say spool characteristics are withing 200 rpm and have seen substantially more power up top. But, the turbo is a little more the the 3076 which may be a factor for some. The OP sure made some good power with his gtx3076.
That's exactly what I was told about the GTX3076 and the 3576 does better because of the better pairing of the wheels and more top end flow. The OP DID DO very well with the 3076 and with stock heads and cams. That is a testament to the DAVCS and Phatron's tuning of the car with some pretty aggressive timing. Look at the torque the OP is making with this build because of the stock cams/ heads and aggressive timing. I also think that keeping the rev limit to 7K is a good idea with the stock heads and valve train!
