FLlegacy Posted August 29, 2016 Share Posted August 29, 2016 After installing my Nameless down pipe I have been trying to hunt down either a boost leak or some other issue. I am maxing out around 15 psi on a 17.5 target boost. What kind of data will show up in data logs that would point to one or the other issues above. What tests can I do besides a leak test, which I already plan on doing. Sent from my SAMSUNG-SGH-I337 using Tapatalk Link to comment Share on other sites More sharing options...
Max Capacity Posted August 29, 2016 Share Posted August 29, 2016 I assume the car is tuned for the DP ? If the air temp is hotter then when the tune was done, won't the ECU compensate by adjusting if the temp and other things have changed by reducing power to save the engine ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

FLlegacy Posted August 29, 2016 Author Share Posted August 29, 2016 I am on the cobb ots tune. I would assume the boost target would change then, and it is staying at 17.5 psi. This issue has been since install. I have tried the hwg and lwg maps with no change. Fwiw, every other install with this dp has had issues with over boost.

FLlegacy Posted August 31, 2016 Author Share Posted August 31, 2016 Isn't the stock one electronic? My understanding is that the grimmspeed and stock bcs are both MAC valves. Sent from my SAMSUNG-SGH-I337 using Tapatalk Link to comment Share on other sites More sharing options...
