Does anyone tune zdyne or have any tips tuning it, i am about to buy a wideband.
I know their are other better choices but i have had this zdyne forever in my car running on the tune that came with it and it has never done me wrong, i just know i can pull tons more power out of it.

Im looking for someone in Cali that tunes zdyne or anyone that has any tips .. Im not retarted i know how to work it, i just havn't spent a lot of time with the fuel/spark since i don't have a wideband.
thanks
