You will need o2 simms with V3...it no longer comes with it...

Sounds like a charge pipe isnt tight somewhere or came off. I had this same problem after my IC install. Went for the test drive, and half engine light came on with a total lack of power.

I'll check the boost leaks for sure. I may be able to do it today if I can get my friend to come over to do it with him, otherwise, tomorrow morning.

Someone on another forum said that I should check if O2 sensors were swapped possibly when DPs were installed (put front O2 sensors on the back or left on the right). Would this cause such a dramatic loss of power (next to no boost)?? I'd think not at all and that in the worst case scenario I'd get codes and/or half engine light and or check engine light.

If you crossed the O2 sensors you would have much more of a stumbling sensation with your car. It would idle rough and wouldnt pull right at all. Another member on this board, asdflkijd had that problem, you can pm him if you want more details.

This evening, thought I'd check all the wires to make sure all of them were in place. So, opened the hood and I just took a quick peak down to the intercooler connections and OH MY GOD!

The charge pipe is completely OFF! I can't believe my mechanic didn't properly tighten the clamps. This is ridiculous.

This will be fixed tomorrow morning. I put the O2 simms back in so after this is nice and tight again, I'm hoping I shood be boosting again

you should of taken it out for a test drive.

Problem fixed The IC silicon pipe came off as it wasn't tightened enough...I'm totally happy with both the UR DPs and the FMIC...you wouldn't believe how it pulls now...insane...now that I've had the chance to see what it felt like driving a naturally aspirated 335i, I'm extremely happy I got my boost back, those turbos do so much for this car its unbelievable...

I dialed down my procede UT settings to 87% for now...I think my V3 is in the mail (got a call from UPS this morning) so I'll probably leave it there and then datalog with V3 and adjust...

glad to see you fixed your problem!! would like to check out your ride, hope to see you around on the road!!

Was the helix install difficult? I believe they said it could be done without removing the front bumper...I was thinking this was going to be my next mod before I get any tune..I know it wont help alot without a piggyback (V3 or JB3) but trying to get the system as effiecient as possible before I put on anything else that increases boost.

Didn't touch the front bumper...only thing is that they say that there is absolutely no cutting involved and I did have to...however, it was a very very small trim of the radiator plastic support bracket that's not even noticeable..otherwise, the IC, the beast that it is, wouldn't slide up all the way into that space...I'll have to dyno to see its affect on performance...i had the DPs installed the same day so this will be a combined effect...

Bottom line, I like it, just make sure that whoever is installing it that they tighten those IC pipes GOOD or you'll have NO boost and will get a half-engine light...

Dont tighten too hard as those clamps will rip right through the silicon hose. The problem with charge pipes falling off is usually because they arent aligned 100% so the silicon hose is crooked.
