I have a car I am going to start tuning that idles at 65-70 KPA. Does this low vacuum signal cause the MAP to trip codes due to a threshold being met? I noticed since we have been pulling the car in and out of the shop that it keeps tripping a MAP code. I think it was P0106..... just looking for a heads up before I chase something else down.

Does {C3003} need to be raised? Looks like it is similiar to the predicted air flow table on ETC cars. According to that tables values, stock F-body, we have exceeded the "predicted" MAP Kpa values vs RPM and TPS..... will this cause a DTC?

Its a 2000 F-body with a D1SC ProCharger on a 408.

Thanks

Howard

C3003 should do it. Also might want to lower C5501

Made those changes as well as a few others related to the MAP. Seemed to be OK while VE and MAF tuning today!

Thanks Andy!
