[ZLAV1N]

So ironically enough, I had this same exact conversation with my builder/tuner at Katech. I am picking up my ZL1 next week but I got the dyno graph today (see attached).

What I was told is this :

"That’s actually the oil pump solenoid tuning on. It creates a momentary dip in the power.

There are certain parameters that it has to hit for the solenoid to turn on. One is oil temp. If he cooled it down a bunch and made another pass it would likely get rid of that but it doesn’t effect power so there isn’t a need to do that."

From my understanding the car drives amazingly well & all other data that was shown during the tune is exactly where it's supposed to be. Katech has been nothing but stellar to this point and this is my 2nd round of mods to my ZL1 with them. The first time everything was absolutely flawless. We'll see when I get the car but I have zero worries and high expectations.

FYI, I have the Katech Billet LT1/LT4 Wet Sump Oil Pump in my ZL1 as well.
