Really well! It'll actually start building a tiny bit of boost as I'm slipping the clutch to get going in my uphill driveway. Really helps it takeoff without leaving behind any smoke. I went from 30.5x10.5 bfg ats to some 31.9s at the same time as the swap so i didn't get a big fuel economy bump. Before I averaged around 21 around town. I got 22 with the bigger tires (diameter/distance accounted for) on my last tank. I was hoping for a large bump in efficiency but I guess I shouldn't complain about 22 with this tire setup.
I've been meaning to post a log comparison to show how much better this builds boost than the stock turbo. If I stomp the pedal ill definitely get some overshoot which is why I havent...need the data to look pretty haha. Ive been too lazy to tune the pid loop anymore and have just been ramping into it...which is how id normally drive anyways.
Glad to hear. It's a great fit for the 606.
The turbine and compressor in those GTD series aren't worlds more efficient than their predecessors, maybe around 5%. But 5% efficiency on those stages won't create a measurable effect on mileage. It's just makes a small difference in how hard the intercooler has to work and the spool time.
