So as many of you who are still on the mhd ots maps may have seen the release of new beta maps from mhd dropped today. So when you update and look at the maps screen, you will find ethanol mixes for every stage. I am currently running v7.1 e60 in my car, however i dont have dps installed yet...

I will be selling my twin setup and some other parts. The turbos were installed on April 2017 they have roughly about 3500 miles on them. Still under warranty although there are no issues with them. Tracked Twice and dynoed once. Well taken care of. Prices are Shipped minus 3% paypal fee unless...

Twisted Tuning's N54 Direct port Meth Injection system is the best performing option on the market for your N54/N55. Direct port injection is the PROVEN best method of secondary fluid injection regardless of what some vendors say and try to push saying chargepipe and throttle body injection is...

I'm upgrading my stock turbos here in a month or so. Going with Pure Stage 2 for sure. Can't decide which one to go with, daily driver (DD) vs. high flow. My objective with this car is to be between 550 - 600 HP. Don't want all of the maintenance that goes with higher HP#'s. Current build...

Hey everyone, so ive been doing alot of digging around the internet the past few days trying to wrap my head around the concept of transmission reliability. I am currently running a 09 E82 6AT that is currently stock! I havent done any mods to it yet and I do plan on doing most of the work over...

I wasnt going to start a new thread but im having an issue, that i just can NOT figure out... I have no power to my interior (E92). No gauges, Gauges, Guage Cluster screen, and there's a constant "relay clicking" noise coming from the JBE area every 5 seconds or so. And currently this will...

Full FBO and MHD Wedge Tune. Was getting super duper shitty gas mileage - we talking 12mpg... Replaced all four o2 sensors and mileage shot back up like a rocket. Now 18-20 city and 23-24 highway. This is with down pipes. So if there is anyone who is wondering if changing o2 sensors after...

Hey guys, new here. Have a 335i 2007 E92 and there's no boost at all. Vacuum lines are already checked, selenoids are working, diverter valves are working as well, we've changed wastegate actuators and flaps, but there's still no boost. What else can we look into? Best regards

Maybe Im not the luckiest N54 owner been having a new issue each month. Couple of days ago i noticed some smoke behind the car when i was going a downhill like 2 min after i warmed up my car and drove. This happened today as well Im not sure what is the problem. The car doesnt smoke at startup...

A little something different for the masses that you don't see too often on the N54 is nitrous injection. There are turbo upgrades out of the Whoo-hah, but we wanted to do something different and go against the grain with this particular 335xi. Setup designed by us here at Twisted Tuning...

I feel like the 1 series form isnt as heavy as the 3 series or anything else really. Im curious to see where some of you guys are from. Post up a pic of your 1er, any mods, and location! Alberta, Canada.

Hey guys, so i wasnt to sure if this was normal or not, but everytime i start up my n54 135i (Bone stock atm), i get this lound raspy rattle in my exhaust. Only lasts for about a minuite or two until engine warms up, then its completely gone. To add more confusion to this all, if during the...

For sale is a set of Molnar Technologies connecting rods. I am using a set of these rods in my high hp build, designed for durability and abuse... they are beefy! The big end retains the OEM spec for bearings The small end is flat for the extra strength and not tapered like oem. After-market...

Hey guys, I created a Tumblr build thread but a few people asked me to do one here so here goes. I have built many cars. Mostly muscle but I love classic bugs and I've even done a couple turbo hondas... Hell, I've had more cars than years of life. I actually wanted a 1er since late 2012 but...

Hey guys i wanted to ask on opinions for quad exhaust set up for the 135i. Im currently running a 09 135i which i am planing on building as a show car, however my personall philosophy is that if a car looks mean, it better drive mean, so while i throw my money at this to look great, i do want...

Just stopping by to say Hi. Lurked for awhile, couldnt find my old account so made a new one. Ill post some pictures of the ride from the laptop! 09 335 M sport. Few mods :). More to come this winter. Stand by I cant figure this out on the cell, nooooooob

Got a used but totally flushed out with fresh ATF and coolant heat exchanger. Thermostat and all is working perfect. It's used so don't expect crazy shiny like in the picture included. That's just a sample image of the actual form factor.

Okay guys I was driving my car a little hard today. When all of a sudden my car went into limo mode. I check the codes via JB4: 2CF9 - throttle valve potentiometer 1 2CEC - throttle valve actuator , short locked 2CEE - throttle valve actuator , running rough 2CF7 - throttle valve potentiometer 2...

Hey guys I just installed the Precision Ignition upgrade on my car. I'm super happy with how the car feels now. I was getting crazy misfires before and somewhat of a rough idle but it runs mint now! I'm also working with EMP tuning so I can get the most power out of it. I made a DIY with some...
