So my auto has a hy35/9cm wastegate. I do run a ez chip. I would like to upgrade due to restrictive breathing. However, my 3.55 auto has a huge bog ratio in OD. I am at 1500rpms at 60 mph. It seems to me that under low rpms with minimul upgrades the "hy" would spool better. So should I just live with what I have now till bigger upgrades or do you think I would still bring down egts better at crusing speed under load? thank you

 

At only 65HP over stock, your HY should flow enough an keep EGT's in an ok range, especially with a J-hook. Regardless, an HX35 would work just fine for you.

 

The HY and EZ are a great combo. Your temps shouldn't be too bad all.

Right now, I running my stock HY-9 with 162K on it. I have dd2's, ez, and a tst comp.(just installed tst). I know I have waaaaayyyyy too much fuel for the hy but boy does it spool quick when that tst kicks in. Hits 40+ psi in the blink of an eye and it's still holding together with not much shaft play. It's a tougher turbo than people give it credit for.
