Hey guys,
new to this forum.
Quick run down of my car
02 4runner v6 4x4 5vz motor - Automatic
Supercharged - 2.2" Pulley - Trans Cooler - URD 7th Injector
I've had the injector for a couple months now, but something hit me and I started reading forums about having to tune your Performance Calibration Unit.
Dang it.
So I've always had this ping problem when I drive up hill on 4th gear and I start gassing slowly and when it hits about 2000? not exactly sure which number it starts pinging and I get no more power, then the car down shifts and we got power again
I was wondering if there are any maps I can use or if someone can tell me a little bit about tuning or if anyone knows where my problem lies. That would be AWESOME!
I've been using the preloaded map that gadget gave me.
THANK YOU!

That should get the vast majority of your questions awnsered. In a nut shell, you need an OBDII logger that can read the wideband and you will have to tune it manually.
