There are two COBB vs jb4 threads right now at the top. I would pm you but I have been removed from most privileges.

You can Google & read for yourself, but the piggys & flash function in 2 completely different ways (specific example: target boost differently). There won't be any power differences with an 335is, 1M or "normal" 135/335, so you can search the forum for any dyno comparisons of the COBB & JB4. My greatest recommendation would be for you to see if there are any people near you that have the tunes installed on their car (JB4/COBB, similar mods to what you might do) and ask if you could go for a ride. Power isn't everything & I can promise you if the drivability is poor that you'll want to shoot yourself anytime you're not going WOT. I will stand behind the COBB & point out that there is a reason why Terry (BMS) offers specific COBB Maps that work with the JB4 when people start running FBO/E85/Upgraded Turbos on their N54s. While the piggys can manage meth & hijack the gauges, they cannot alter fueling tables or engine timing (which IMO is much more important). To each's own though, I should be posting some dynos & my PTF review by the end of the week after I hit the dyno tomorrow, so keep your eyes open |

If you have to choose just one, a piggyback will net you more power out of the gate with less work since autotuning has gotten very good. With the piggies you have to rely on conservative maps or do a remap every time you get a new mod. Eventually for FBO+ and E85 you will want a flash and the piggy to get the most out of your car. So my advice is to get a JB4/Proceed first for autotuning and then stack a flash if you want to later. There are separate benefits to both and no disadvantage to running both of them. So in a cost unlimited world you would have both. I personally only have a JB4, but plan to get a flash eventually if I want to go past 50% E85.

OP, that's what I did (Cobb), and I love it. Exact same reasons as you, and no regrets. Car feels fantastic.
Get the flash, and have fun and be safe. This platform has graduated past the piggyback and into flash land. Like other platforms, the piggy folks will die hard, but no matter. Not sure why the fanboys bother. The OP specifically said he didn't want to screw around under the hood. |

About graduating from piggybacks, I disagree, the flash and the piggy back bring something to the table. Pretty sure you're being a fanboi if you cant see/admit that. A piggyback is a better intro tune than flash due to the autotuning, gauge features, meth, etc. The flash tune shines at additional fueling, timing, and VANOS. Ideally you will have both unless you're poor or don't plan to go deep with power. |

Is about to enter the N54 market. Piggys are great, but they have a lot of limitations with in-depth tuning that only flash (or standalones) can address properly |

FWIW, this platform pretty much has gone to flash based tuning. Vishnu and BMS are basically using their boxes as a boost controller/meth controller/NLS/WOTbox at this point.

Like I was saying, they both have their benefits. You will want both to get the most out of the car. The piggy is still a better starter tune due to autotuning, nls, gauges, meth, cost, etc. The flash really excels at cleaning up fueling and the calculations the ecu is better at handling such as timing. Before large turbos or over 50% E85 you will typically see the piggy make more power with less drivability. Considering you can stack these two, I haven't seen a legit reason why it makes sense to force yourself into choosing one or the other. You really should have both.

It's not that I'm lazy. I've experienced piggy backs before with my 3000GT VR-4. I ran Greddy E-Manage Blue with the a/f and timing tune. It was fine but if the temperature changed I had to get another tune since my car wouldn't adjust. During pulls, I had to keep an eye on my A/f's, EGTs, and Boost to make sure things were in working order. I did a lot of work myself except when it came to heavy duty stuff or wiring. I popped the motor just by screwing up one setting on the boost controller and it was enough to cause me to run lean and detonate I didn't catch it in time because first and second gears were so quick I didn't have to to glance at 5 gauges. Overall The car was a blast and ran mid 12s consistently. I replaced the motor and sold the car.
I don't want to go through similar tuning issues with the BMW. I like the way it drives stock. Ultimately, I would like more power but keep the stock drivability.

stock 335i with intake mod
Guys, I'm new to the forum, so hi. Coming over from Mazda... just purchased my first BMW - and its a 2008 335i with 53k miles (picked it up for 19500 with convenience feature, nav, sport, etc).
So the power stock is amazing vs my mazda. However, I'm about to bust a nut to get more power and less hesitation when I step on the gas. So I ordered a Cobb accessport (friggen expensive) and a AFE Magnum FORCE Elite Stage-2 Si PRO 5R Intake. (friggen expensive, but wanted a closed system vs open.. just looks better and seems like it would suck less hot air vs open (IMO). So from those of you who have Cobb and possibly this intake - what map stage should I use and what should I expect? Also, going to do the walnut cleaning this week and the oil gasket replaced - worth the money? Looking at about 700 for the service... I heard walnut blasting really made a difference... (well heard it from the guy wanting to sell it to me). Thanks in advance... |

Walnut blasting is definitely a smart thing to do with 50K+ miles.

What is the opinion of the intake? In your opinion, do you think it was a good choice? (vs the 2 cone open system). I also unplugged that exaust port cable in the back of the car to make it sound better. Assuming that won't do anything to HP - I am not ready to get a new muffler yet... I don't see the gains that are worth the 1000 plus dollars to do that... So what HP and TQ do you think I should expect with what I have on the stage 1 agressive? What do you need to go to stage 2? I think this 335 has the intercooler because of the sport package... just not sure how good the injectors and coils are since I purchased used.. plugs were changed at 46000 miles by BMW dealer with previous owner. |
