I don't believe that the stock DP is the reason for the low WHP numbers. The main reason is California's shitty 91 octane piss fuel. I just moved from Miami to Sacramento in July and the difference between the 93 and 91 is day and night. I dynoed my car in Miami on 93 octane before I left Miami (98 degrees 37 humidity). My car had the following parts installed: PTF 93 octane tune, stock turbo, ETS 5" FMIC, ER CP, stock DP and stock exhaust. Running California's 91 octane with the same bolt on's, I have consistently struggled with misfires at low rpm in gears 4,5 & 6. I am currently working on an E50 tune with PTF.

One thing that hasn't been mentioned or explained but can be seen on the dyno is that with the stage 1 turbo there was actually more torque at lower RPMs. The car did actually feel a little snappier around town with the stage 1 than the stage 2, but out on the road the stage 2 wins hands down.

I've got 93 here (OH) so not quite the issues you have - but there's only one E85 station here so I'm likely to need both a 93 tune and a mix E30 or E50 tune down the line. I've got CP, 7" FMIC, DP currently. Holding off on getting a PTF tune until after I install turbo.

I'm xDrive so I'm tempted to just go stage 1 (labor is about 4 hours stage 1 vs 10 hours stage 2 from what I hear) since I have someone willing to do it for cheap. I'm assuming that if/when I do this, I may end up still wanting more power as my goal is to make about 450 AWHP preferably on pump gas. Snappier ride around town sounds great though.

You have better gas than me and you have a DP and I don't, so I have no doubt your gains would be greater than what I saw. I'm still in early stages of E50 tune but definitely pulling harder at lower RPMs than on 91. If you can wait a while I should have another dyno to show with better fuel at some point.

Like I said, the only reason I bought a stage 1 in the first place is that the stage 2 was not out yet. Stage 2 is not sluggish around town by any means even on crappy CA gas. If you can afford it I'd go for stage 2. If you get stage 1 you'll be happy but you'll always be wondering how much better it could be if you had gotten stage 2. But I have no idea what the difference would be on x-drive vs RWD.

You are leaving alot on the table running the Cobb OTS tunes. PTF used to charge $200 for E90post members for their protunes (They may still). The difference between the Cobb OTS and protune is day and night. The protune is very refined, it eliminates all the timing drops (the choppy throttle response, not to mention it increases the boost quite a bit over the OTS tune). The OTS tune in my experience felt very choppy, unrefined, unfinished and underwhelming. The protune felt very refined like the OEM tune with a lot more power. The increase in power and refinement is well worth $200.

It says in the OP that they're custom tunes by Dzenno at PTF.

No rush on the fueling at all - I haven't looked yet into getting any e85 added in for a protune just yet and my time is dwindling (winter will be here before I know it in Ohio )

I definitely think long term I'll wind up with the Stage 2 if the power gains are that significant. If I could get a Stage 1 installed before snow fall though that'd be nice.

I'm fairly certain they still do. It was always part of the plan to get a PTF protune. I was just holding off since I was anticipating a quick transition to a Stage 1 turbo.

There's an xDrive N55 Pure Stage 2 pushing 458awhp and 488awtq on just 93 with a protune.

That's exactly my end goal. The only reason I'm buying the Stage 1 first is in case I get bored and want to feel a bit more power in between saving up additional funds to prep the car for more power I'll do stage 1 soon then opt for stage 1 once I've done some more braking/suspension upgrades I have on my to do list.

Very nice to see some numbers on normal gas Getting tired of looking at these crazy results from race gas + meth etc etc. - not exactly DD doable.

Its very DD doable for me

Who did your tune? What were the ambient and IATs? Those are insane numbers for 93 octane in a stock N55 engine, especially compared to what I got with 91 octane and a stage 2 turbo.

I ran 17 psi from 5k till redline only 93 octane with jb4. Its good for 450-460 whp.

How come dr robert got 330 whp on stage 2 turbo 91 oct and you got 450 whp on 93 oct with also stage 2 turbo ???! I know you got a downpipe and he dont but his car must have somethung going wrong right ?

His octane was more like 89 octane and his dyno reads low. He was running low boost at high rpm.

If I'm not mistaken he has a protune by PTF.
