Actually I am not leaving anything on the table that I want, or need, right now. While the JB4 can jack up the boost, I am currently happy with 15 psi. Darkhold has already agreed with what I believed the results are, probably 410 or so. With the Dinan Stage 3 tune it pulls right up to red line. People here trash the Dinan, saying that it dies out at 5 k. They are confusing the Stage 2 with that. DarkKnight can concur. I now have a very fast bimmer. Is there power left on the table? Yes, but I can have my broken down CPO car towed by roadside assistance to any BMW dealer at any time, with no CPO concerns. Who here with a modded CPO 335 can say that?

In a year or so I may want a bit more. At that point I may get a JB4, an ****** CEL free charge pipe, and add 3 more psi to bring her a bit higher. 460? As far as e85 and meth, that would be wild, but not for me. Yet! At 20 psi these cars must scream. At 23 + I would not drive, or even be in one without a helmet. I'd expect those cars to be close to high 10s. That's scary fast to me. And would most likely require suspension mods that would make a beautiful riding car end up having a firmer, less comfortable ride. No longer a BMW to me.

With each 1 psi I estimate you'll see about a 20 hp gain, however the supporting mods are put together. If I had a downpipe I guestimate that I'd be at about 430, which lines up with the 530 numbers at 20 psi. The mentioned 630 hp with direct port injection e85 will probably be 25 psi. Maybe Jesse or Darkhold can confirm my assertion.

Anybody that is on the fence of getting Stage 2 vs Stage 1, go with Stage 2. The money you will not be spending by ending up doing the second install a year from now will be applied towards the cost of the costlier stage 2. So you aren't FBO. Even with a tune and a charge pipe this thing will work fine, so put those concerns to rest. Then you can later do the downpipe, further increase the boost, and really see your ride scream.

My car now runs smoother, and a slight hesitation I used to have when taking off from a stop sign is now gone. As long as I stay out of it, which is impossible, I am getting better gas mileage. I say that since when driving at 80 on the highway my miles to empty is like 30 or 40 miles higher than it was on stage 1. Maybe Jesse can comment on these possible side benefits. All in all if you intend on making your 335 faster, heck, as fast as you care to ever go, this product should be up on your list, right next to a charge pipe and a basic tune. You can then grow the power as you go on, and your sensitivity to CPO concerns fade. The only thing you'll look back at is the mouthy N54 guys with FBO in your rear view mirror.

Has anyone reached the 600hp range with this turbo yet?
Also does anyone have any experience without upgrading the diverter valve? In wondering if an upgrade is nessesary

If you are looking for big power, I would definitely do the DV. If you are talking 600hp, then yes easily. If you are talking 600whp, then no. It seems to be topped out around 560whp. That is still really impressive and would be a mid to low 10 sec car if it could hook.

One dyno was just under 600whp I think it was 595whp. The guy crashed his car a week later but I found it on Instagram and asked a few questions. He was running port injection and maxing out the turbo. I'm not sure what boost he was able to hold at redline. I would say most will see 500-550whp.

Installing the turbo as we speak. I'll be doing a pump 93 map and E30. Once I put it on a dyno this summer I'll post some logs and graphs for everyone to see. I'm not going PI, but I am add meth later this year. My car is FBO. So I assume I should be around 450whp on pump alone. But I've seen 420-460whp on graphs from E90post/N54tech.

94 oct pump and vd says 380 whp which is about right since i run 100% meth and pwm is maxed out from 4500 rpm to 7000 rpm its maxed out i could had a bit of timing but i wont see more hp i.think

If i install a tmap sensor i could go 23 psi for more torque down low maybe
