Single turbo Nismo

Flyboy

No experience, but I am looking at going turbo, and they are in Fl like me, only 5-6 hours away, but I'm not going to go spend 8-10K on a kit that needs a retune 300 miles later.

The first question was just that, a question. I didn't understand the need for the retune.

I would love to know myself...But nobody Z1 can send me logs to where we made a mistake. we tune a LOT of cars and never had a cust get a retune. I stand behind my tunes and our builds 100% Our Dyno is the most used Dyno in Tampa. there are times we have tuned 20 cars in a week.
My Tuner has tuned cars in the 3000hp power range. We are humans and there is going to be mistakes.

By the way his A/F was 12.2, that is not that high, that can be the difference between two different WIdebands? Two different Dyno's Two different states?

There is a lot of different type of conditions.

Well since you live in Fl. you remember that tropical storm we had couple weeks back? i tuned that car during the storms and my dyno was flooded. the weather was intense and I think thats why are tune was off.
