Boost/hps issues, need suggestions.
I am currenting having problems with my hp at 14psi of boost. I pull strong at around 10 to 11 psi of boost and after 11psi, my car does not pull as hard. I am hitting 14psi, I checked all the couplers and BOV, but still cannot find the problem or any leak.
I am going to check out what the problem again this week. Herbenny and I will diagnosis the MSD ignition or spark plugs, but if anyone has the similar problem, any suggestions would be greatly appreciated. Thanks

If you are running your stock turbo's your turbo's may be showing wear and causing inefficiency. Check the shaft play on them. This is just an idea and I don't know if it is the right place to look.

Thanks, I will check in on that...
Oh yeah my idling is also really rough, it fluctuate a lot. When I set the throttle at 1200rpm, it will stay for a few days and then start fluctuating below 1000rpm. Then I have to set it again.

I actually have someone's basemap on there. I had it tuned at 11psi at 300rwhp. Even though it is not fine tuned, it should be around 340rwp at 14psi.

If you are reading 14psi off of your PFC and that is your only method of getting a boost reading then I can almost guarantee you that reading is wrong. You really need a boost gauge to effectively read your boost and a separate boost controller to control it. The PFC's boost reading is known to be off. You are probably over boosting and leaning out.
I agree with rynberg that your problem is most likely a tuning issue.
