I live in DFW so its a cluster of small cities and freeways. Its a combo of both. Also if I am driving the Z, then I taking it out to have fun and I am romping on it pretty hard and at every light lol. I would stretch it and go as far as saying I CAN hit around 10-12 if I really baby it but most of the time I can almost watch the gas gauge drop when I am WOT.
I could have some tuning issues, car isnt as peppy as I would expect but no smoke or stalling with rock solid acceleration and idle. I am looking to order a AEM UEGO this week and get it installed. Never had the car on a Dyno or hooked up to an A/F meter. I am running a JWT chipped ECU also and from what I hear they run pretty rich.
