Exactly. He's stating flywheel power, or his "tuner" told him those power numbers and he's ( @Kizzu) confused.

I apologize for the mistake of saying that. I rephrase. my car is doing 215ish at the wheels. I still get confused between crank and wheel power

Do you have pictures?

their printer wasn't available but I took a photo from my phone
running on 85/87 octane and ambient temp is 83F

Which puts you ~211whp.

Can I achieve ~225 whp with this tune but a different intake/exhaust setup?
Currently I have an injen sp series and a bone stock exhaust.

The Injen's larger pipe diameter probably does contribute to some low end power, and when cool, more power overall. However, when I tested it, as the car got hotter, it lost more and more power. A heat shield is a must with that intake.

It's very true indeed! But apart from the fact that it needs a PROPER heatshield, I think that something to insulate the pipe itself is needed or else a plastic tubing don't know which is best

If by exhaust you mean headers, yes. Otherwise not much out there in terms of significant power gains left for you.

See my recent dyno thread:

Saw it already tbh and it's amazing ! Good job for that. But sad news is that I don't really afford a 1.3k headers. So my alternative route is to decat my stock headers and IF it does not get too loud remove muffler aswell. Regarding air intakes, what system are you using if it does not bother you sharing ?

I use the euro box/euro BMW performance intake. I really doubt it does anything.

Muffler delete on a decat will be absurdly loud.

But will i see some decent gain?

From the decat yes.

Okay then I'll be looking forward to this mod prettysoon

does it take the computer 400KM to adapt to anything? lots of people on the e90 forum are convinced that all it takes it 3 WOT pulls in order to adjust timing to compensate for a modified flow in the exhaust system. I am 100% convinced this is not true because when i deleted my secondary cats, My exhaust note sounded much different 400KM into the process vs when i first had them removed. what do you think?

Yes. That is what my German tuner told me. He was located South of Stuttgart about 240 kms from where I live in Bayern. After driving back home and a few days later... I did notice that my engine ran/pulled harder in gear than it did just after the tune. To be honest after the SW tune was uploaded... it did not "feel" that much stronger than stock(before). But after a few days of driving, the car definitely was making more power than my tires and rear suspension bushings were protesting under the (new)power.

I am still happy I went with my SW flash tune. Almost 90K kms of no troubles or engine check light(or shadow codes). I couldn't be happier.

I think it does take 400 kms for the "tune" to adapt to the engine/fuel/altitude/etc.

just as i thought. let the e90 guys do whatever they want with their ecu. looks like i should be spending some more time with the 1 series fellas.

what do you think about an ECU tune? how does it stack up in terms of long-term reliability? im looking to tune my ECU soon, but i had a friend advise against it because they are messing with the factory fuel/ignition timing and then i've had another friend tell me also not to do it in fear of my automatic 8 speed shitting itself. what do you think? should i do it? I want to do it because I have a 3 stage manifold from the factory and my 3 stage (45000rpm+) is not fully optimized, therefore why I have the 330i torque, but not the 255hp high end from the third stage of the manifold. what do you think?

thanks!

I have friends with 128i's that have installed the three stage intake manifold and disa valve. That really wakes up the 128i to 130i horse power levels. But its not huge numbers like with a tune'd 135i. Still I would go for it and do it. I think its like 30 Hp which is nothing to sneeze at!

Maybe smellthebeans can chime in.

ive already got a 3 stage from the factory. I will be going an ecu tune to fully optimize for it soon. how much power can i expect from an ECU tune? will it be reliable for my engine in the long run?


damn, i can smell the beans from all the way here. jeez.
