I should have rephrased my question - is 94 octane gas (spiked with 10% ethanol) suitable for the 93 octane maps? I'm erring on the side of caution thinking that maybe the logs (if they exist) suggest that the 94 w/ ethanol is more like a better 91, but not like a true 93. In other words, is 94 w/ ethanol less awesome than true 93, and therefore should I stick to the 91 maps when running that fuel? Sorry, a lot of words trying to ask a simple question |

If the protune qould be able to extract that much more,then who needs meth if you can make 440 -450 tq all day on pump.I heard that a cobb stage 2 + aggressive on a fbo completely catless make 418 all day on pump gas..this true?

Lets just say S2+ FBO would trap 117-118 all day on pump. These things dont dyno as good as they actually run. all dynos ive seen are around the 390whp dynojet, a bit less on a mustang.

There's a dyno over on 1addicts of a stage 2+ car putting down 420rwhp. But im almost positive thats either an optimistic dyno or a dyno operator skewing the results.

if i can make 345 and 410 on that same dyno i'd be pretty happy, which is why i'm asking if simply getting protuned would net those numbers since stage 1 technically is not "mapped for my intercooler". |

Why don't you go dyno instead of speculating?

The 1 series makes more power then a 335i.The 1 exhaust is a bottle neck,when the rear cats are removed it makes 15 whp easy.The 335 doesn't see that gain cause the oem exhuast flows better then the 1 .Yucci made 417 whp and 466 tq on a sae dynoject on straight pump 93 oct.The jb4 is fairly weak when compared to the cobb.The stage 1 aggressive feels stronger thhen the map 2 jb4 any day of the week.The jb4 gets more worried about their afr's.Richer=more tq and a cooler running engine.

Yuchi is a personal friend of mine, So i'd know better about her car than most people on here. I have JB4, DCI, fmic, and downpipes. I was on map 7 (98 octane and 16.5 psi), our cars are very similar in terms of speed with her maybe edging out way up top. Her 135i has the same mods as my 335i, except she has an aftermarket catback exhaust and is running the COBB stage 2+fmic aggressive tune on 93 octane. Her car hits about 18 psi. So by no means is the JB4 "Weak" as you claim. You also claim that terrys customer service is bad. He helped you by referring you to links with all the information and suggested solutions you needed to resolve the problem you had. He isn't superman. All you had to do was READ. So because you didnt feel like reading or putting a little effort towards solving your problem, his customer service is bad? Nah, I don't think so. Also, stop bashing tunes after you buy and then sell them. If you dont like a tune , fine, but dont go out of your way to bash or emphasize how "bad" it is to you.

I have been in the game for years and had over 10 turbo cars ranging from custom tunes ,self tunes ,and pro tunes.If you try to compare this tune to a Cobb ,you simply can't ! It out spools it and makes more power in every rpm more then the jb4. A form is entitled to options and reviews .Just because you have the jb4 doesn't make it the best.I had it ,and of it was I would have never had sold it.The jb4 is Budget tune with a kick,but for the money it ok. You might have thought his customer service is top,but I don't.I had emailed back and fourth for things ,with him responding useless help most of them being a link without even having a proper link attached.He basically g. L finding it. Now I know ,if there's no number to contact a company you'll never have the best support.These companys with no contact numbers are fly by night .
