Charge pipe/ Diverter valve worth it?
Is a chargepipe/diverter valve upgrade worth in on the N54?
Anyone have any real world dynos showing a power increase? Just seeing what should be next on the list. So far i have: -Cobbv3 tune -Remus axelback -Wagner FMIC -Wagner catless DP's -AFE Intake Going to stick to bolt-on's. Dont want anything too crazy.

I have the ER charge pipe with HKS BOV, I don't think you gain much from doing it, but I like the sound of the BOV. For that alone its worth it. The factory charge pipe is plastic and can fail when you run higher boost. So its a worthwhile upgrade for modified cars.

I have the ER charge pipe with a Tial blow-off valve. I don't think it adds any power, but it was easy enough to do when I installed the intercooler. I liked the idea of simplifying the intake plumbing by eliminating the two recirculating valves, and also liked the idea of all-metal tubing instead of plastic. The sound is a nice bonus, too.

I have an ER charge pipe with Forge DVs. Most likely it is from the DVs, but I feel the car is smoother. Not a huge difference, to me it was more about eliminating the weak links after doing the ER intercooler setup.

I had issues with the ER Chargepipe on my HPF FMIC. The HPF FMIC uses the stock connection and the ER Chargepipe did not work for me. I decided to use the stock Chargepipe and I went with the Turbosmart BOV and it works great. It certainly holds the boost better than the stock DVs and you can change between BOV and DV.

I ran ER all the way. ER Charge Pipe w/ HKS BOV and ER FMIC. Bolted on with no issues. Love the sound of my HKS BOV.

Is you HPF 7 inch? Maybe that's the discrepancy? |

I had an N54 135i (JB4,Charge Pipe and Catless DP's) ran well and now an E89 N54. I put the JB4 in it and had under boost issues. Waiting on AR Catless DP's and the charge pipe to come in. I ordered it with Forge DV's (Suggested by Mike at N54tuning.com) as running a Tial BOV is better if you are running Meth which I won't be. Hopefully the under boost issue will go once I put the aftermarket charge pipe on (based on the plastic stock charge pipe theory)
