I finally fixed the issue on cel with Custom DP. Terry's O2 simulator will fix it.

My o2 sensor throw cel because i dont have cat on my dp. Yesterday i drove all the way to Terry's Home to get the o2 sensor custom simululator. He installed for me. We test drive my car to see any repeating o2 sensor cel related. There is no cel throw by the o2 sensor. i m very happy. I also notice that my gas mileage goes up. Terry is very friendly guy. Too bad i wish he have more hair because he look like matt. lol. i asked him to help me update the vishnu firmware for me. He said i dont want to deal with vishnu stuffs. I totally agree with him because they have been too many fireware update and map update. Dont get me wrong folks, im still Vishnu Fans because they make the most power. Juice box is very good too. however, they make a little bit less power than vishnu. He said since you are a cool guy im going to help you out, but i dont like it. I think it work now. NO Terry did not use vishnu data to enhance his juice box. Personally in my opinion, Terry does not care much for vishnu stuffs. Terry have his client to take care of. If Terry have release his juice box first, i would buy his stuffs because of the low cost of the juice box over vishnu procede. We use his laptop to observe boost level on vishnu 2.0.2 with speed limited map. It does not stay at the level at high rpm. It switches from 14 psi to 10 psi and back .. I dont know if this is a good thing. Normally, boost level should stay the same at high rpm, but not with vishnu v2.0.2.

People who are planning to install custom dp, i suggest to contact Terry for his custom o2 Simulator. it cost ya 100 dollars. it look very easy to install. Dont go to any performance shop beside terry because they will tell you something else to fix it and they will charge u big time. I happen to me. i dont want anyone on here to get overcharge.

Here is a quick question for shiv why the boost level switching so many time. should it stay at the 13 to 14 psi at high rpm? on the firmware information. it said 1.03. is that the new fireware that u released to fix limp mode on v2.0.2 ?

YES the boost is supposed to taper down at higher RPM's, totally normal, that is what it does stock. I'm surprised Terry didn't tell you that.
