So what can I add to improve my 0-60?? I already have dinan stage 2, does cobb or jb4 goes well with dinan? Any additional mods I can have that are not too expensive?

Thanks

Cobb will overwrite the Dinan flash same as the JB4 ISO file. Both are far more aggressive and equally safe to use and will be an upgrade especially if you have an FMIC.

Dinan is much more expensive....how can you say that?

No. Dinan is reassuringly expensive, and must be better their either on their best day.

If you like your warranty you can keep it, if you like your service advisor you can keep him/her.

I think you need to re-read what I wrote lmao.. He said he already had it and asked about cobb and jb4... I simply stated the cobb and jb4/iso file would overwrite his tune and said nothing about cost other than they are perfectly safe and would provide an upgrade over what he's seeing now especially if he has an upgraded inner cooler.

Trying to get a build slot for the huracan is proving to be just as a PITA as the 14' GT3

IMHO the Huracan is a better looking car. No need to spend 450-500; it might be the base model but it looks like the pick of the litter.

BTW I think there have been instances where a stacked JB4/COBB did not play nice with Dinan. I know the Dinan listing is no longer on the JB4/G5/ISO menu.

Well, see, 'both' meant Cobb & JB4.

But they're 'both' so much less costly that Dinan just has to be the best!

Yeah they're both better lol. I was just saying Cobb overwrote my Dinan when I went over it... Since JB4 is a piggy and not an actual flash tune, I'm guessing you'd need the Iso file to actually overwrite the dinan tune.

No experience with dinan or jb4 but Cobb did not impress me at all and sold it after a few months. It just doesn't do it for the 335is. It feels stock the car has much more power. The unbelievable torque from 1500rpm is lost, and lots of hesitation at low rpm. Maybe a pro tune will fix but now you are spending almost 2000$ for both cobb and pro tune|dyno service. I heard jb4 is good, a few guys run it on their "is". I also assume dinan stage 2 is an improvement as its made for the "is" only.

I can't comment on what the Is's feel like from the factory but that should have been a nice bump... You'd have definitely felt a bump if you did downpipes and intake and did stage 2. You probably would have been equally unsatisfied with JB4 as thats only a few more hp compared to the cobb at that stage of bolt ons.

Everyone I know with FBO 335i/335is have been very happy with jb4/cobb.

Yeah...no nice bump for me. Nothing compared to stock. I'm not tracking my car so i dont plan to add anything else. Also lower rpm boost is important to me on the streets you should experience a stock "is" when u can it made me choose it over the M3

Basics. The 335IS is a lot stronger than the 335I than BMW's published numbers would suggest. On a DynoJet the spread is about 45whp (51bhp) not the 20bhp in the spec sheets.

If the COBB was falling short it could have been the map chosen. On the JB4 even though map 1 is only slightly stronger than a stock 335is it's a nice step up for a 335i. Map 2 would be the basic map for a pure stock 335is if using the standard maps with the older system. Map 2 is the down pipes map for the 335i. The base COBB map might not be strong enough to make much of a difference on the 335is.

The key JB4 map for the 335is is map 6 which is a custom map by Terry for the IS, 1M & Z435is series. This should generate 365/370whp with 93 octane gas. I use this map + 2psi additional boost + the COBB with a custom map designed for stacking the JB4 & COBB systems on the 335is.

Can't say much more about the COBB package because I have never used it as a stand alone unit but have to think they have a Map that would generate at least 40whp more than a pure stock 335IS.

EDIT: hope its a little clearer.

I guess I need to try the setup you are running. Im still not clear about the torque at low rpm, is it as strong as stock at about 1500rom? How much is the Cobb flash in addition to the jb4, or is it free? I assume you customize +2psi yourself. If I do order it I'll just call Terry and say to give me what Kevin has

The BMS flash is free, just email Terry & tell him what ecu you have. Cobb tells you that. The +2PSI will need better gas than 93. I run 93/100 50/50. When you select 335is as your car in the interface Map 6 IS is set automatically. To raise the PSI it's a change the number in the boxes exercise in the JB4 interface.

I would run default to establish a baseline & create a log. Raise the PSI .5 at a time log it & send the CSV file, extracted from the interface, to Terry & he will give you recommendations what to change. All changeable values can be done by the user through the interface.

Yeah our buddy runs a heavily modified PTF 335is and it is M5 worthy so don't give up yet. Take bears advice and don't give up



Heres the video of his car vs. a "eurotuned" [more like press file fake tune] 2013 m5.
