370z vs 335i Coupe

It's hard to compare an OEM NA car with one that is F.I. Any F.I. car will make more power per mod. Once the VVEL is tuned I think the Z will be able to make even more power, both NA and with those who choose to go the F.I. route. But other than Porsche (and BMW wit the E46 M3) I don't see many other cars with so much power out of the box from a 6-cyl engine. Also, the Z has been shown to make 40 whp gains with intake, exhaust, and "tune" (just to smooth out AFR). I have a very long daily commute to work, and even on the freeways I dont have much chance to open the car up. I don't have much use for anything faster than this, even though I will be doing some bolt-on mods.

It all comes down to personal preference. I don't think anyone's "hating" on the 135i. Different strokes for different folks.

Right now its just AF ratio, timming and a few other little adjustments...and even for what it is, it still makes decent power on a tune. Second, you need to realize that your "just a tune" is for your TURBOS! You have what 300hp/300tq TWIN TURBO charged straight 6 right? Well of course a tune is gonna do allot for for you, you have (2) huge power adders right there. That straight 6 motor with out the AID of turbos wouldnt tune for than 10-15rwhp. NA gain VS FI gain is a retarded comparison. In fact i dont know any motor in the history of man (maybe you can enlighten) that is NA with "just a tune" that picks up over 150rwhp. Your tuning for the TURBOS not the motor...that motor is nothing more power than a Scion TC without the turbos. Third, about the handling, you say that with just sways and this and that you can keep up with a 370Z..? Am sure, maybe, but what 370Z is gonna stay stock anyway?! Stock for stock, mod for mod the 135I will not outhandle the Z.../

So you're saying that just by turning up the boost you're gaining 100 whp? I doubt this, but if so, what is the stock boost? And what boost is the "high" setting? If you're gaining 100 whp that has to be a difference of almost 50% boost or more, which in every other stock turbo car I've seen, would need bigger injectors, fuel pump, oil cooler, and FMIC to operate without heat soak, knock (there must be a timing advance in this tune - there's no way it's just from increased boost), etc

I don't know what I could have said to make you this angry over it, but I think it is more fun to spend a couple thousand dollars or so and pick up almost 200 hp at the crank (Tune + Methanol Injection + Bolt Ons). What does $2000 bucks get you in the Z...30whp? That's what I'm saying.
