Harte Nissan did the install of the kit. There is a lot of wiring that must be done with the kit. The quality of the wiring performed by Harte Nissan was substandard to say the least. We weren't able to tell how bad it was until we untangled the spaghetti they left.roy365 said:i'm confused. Pardon my ignorance in advance, but you seem to be hinting that a dealership could have wired something wrong? What besides the piggyback is needed to be wired? Fuel pump, regulator???? But you dont mention that. And how did a dealer override the PNP Stillen piggyback?Sounds like Stillen is having tuning issues to me. So did you tell the dealer what A/F ratio to run??? If not you have some damn good techs at your dealership.
The dealership did not override the p-back. I logged some data and sent it to Kyle. He in turn gave the data to his R&D guy and fixed the problem via a new p-back, tune and harness.
The tech and I believe it was actually the hack of a wiring job performed by Harte Nissan that caused the lean condition. The wires seemed not to be making connection all the time. Fuel pressure went from 70 psi @ idle to 40 psi @ WOT.
