• Trouble in paradise? Vishnu/FFtec N54 335ii Single Turbo kits experiencing issues as a BimmerBoost member runs 12.5@121 with misfires and having to short shift

      BimmerBoost would like to thank member GeorgiaTech335Coupe for his openness and honesty regarding his Vishnu/FFTEC single turbo setup. Recently, this member took his single turbo upgraded 6-speed manual 335i to the PBIR (Palm Beach International Raceway) dragstrip in Florida to do some testing. His best run was a 12.50@121.6 alongside a 12.8@117. Yes, these times are quite a ways away from the 10.8@131 glory pass from Vishnu demonstrating the kits capability.


      This is in no way the fault of GeorgiaTech335Coupe who experienced misfires on his car and had to short shift at 6300 rpm in order to avoid them. Now, Vishnu has basically portrayed this kit as perfect and ready for sale with nobody having any issues. The reason BimmerBoost is bringing this issue to the attention of the community is for potential buyers to understand what they are getting into.


      There is absolutely nothing wrong with having issues when modifying a car to this level and BimmerBoost is confident Vishnu will resolve them. There is something wrong with pretending nothing is wrong. A few cars with the single turbo kits have gone up for sale and apparently a total of three people, that are willing to open their mouths, are having misfire issues with these kits.

      These issues will no doubt get resolved but potential buyers and current customers needs to be aware of the process, effort, and that progress is being made. Pretending nothing is wrong and collecting money simply is the wrong way to go about this and once again (it's becoming a trend) BimmerBoost is the only site bringing these issues to the attention of the community.

      For the record, a member by the name of @tmo335tt says he has a hardware solution for the misfires that he will likely share with Vishnu (hopefully not for free). Interesting that it isn't Vishnu but the community solving this.

      Thanks again to @GeorgiaTech335Coupe for sharing his details, good or bad, as we all learn thanks to honesty and openness. There is more to tuning than just collecting money.

        Based on all the work I have done over the last month dealing with this issue.

        I've been through everything on my e90 and it has been a very frustrating process. There are a bunch of computer jockeys on here that take cheap shots at people and start fights to try and make a point. I'm not one of them and I don't help people like that.. some dick earlier was saying he guaranteed that the problem was too much meth. Lostmarine tried to jump in and pull up my old posts as if he was going to jam me up but he didn't know that I have two 335's. The bottom line is that the guys who are having the misfire issue will get their problem resolved and the rest can try to figure it out themselves...good luck. Also Dzenno will be happy to find out that I figured it out. I appreciate all of his posts that were helpful and at least he was wrenching and not just posting BS.

        I have no doubt it will be resolved I just don't see how can you say it's not a tuning issue when it seems the answer right now is in the software.

        You will know in time but I promise you that it is not a turning problem. Dzenno has the problem and he doesn't have a procede. It would be wise not to jump on the tune as the culprit, it may save you from eating your words. Take a poll as to how many guys have actually opened up their motors themselves, I bet you can count them on one hand.

        I'm not jumping on the tune I'm saying it seems the current "solution" seems to be through software. So then if you think you have this down hardware wise please share now.

        How many guys have or have not opened up their motors is irrelevant.

        Its very relevant, I bust my knuckles and work out my own problems and some Dbag on here just talks $#@! and hides behind his computer and has no real useful info. I will help out but as you know Dzenno spent a lot of time trying to fix this problem and so did I, I haven't shared this info with Shiv even as of yet.

        Why are you putting in the time on this and not Shiv? Shouldn't he be married to an N54 until this is solved?

        We can't guess, if you feel hardware is involved please share. Dzenno's "solution" was software related.

        I put in the the time on this because I can't sleep when my car is acting up and I don't know why and no one else does either. The only way to fix something right is to do it yourself. Shiv would have been married to this problem but there is a reason why he never experienced it with his car.

        Dzenno's problem was not software related but he was able to use software to work around the issue.

        The problem is 100% hardware related.

        Really interested in the solution. I've got an early 2007 6MT and haven't had any problems since the single conversion except having to replace the coils and O2 sensors. Other cars like FBIS are 6MT 62mm and run fine, so there must be a hardware difference. Good luck to you @tmo335tt.

        Yes....I bought the gray car and ST for shift sector and then spent the whole day watching you race. I'm selling my original car, i was just waiting to fix this one with ST first.
