I believe it's time to update your list of "top tuners." George and the team at National Speed are the best tuner shop I have been to on the east coast.

 

based on these results i wouldn't doubt they do amazing work. Hopefully we can see more amazing work from them in the future and also long term updates

 

I am having the Haltech put on my Z and tuned this week. Hopefully more good numbers from National Speed to report soon Doug!

 

Hmmm, maybe he can still generate some curves for me. I never saw where he put the AIT sensor. Hang on, I think he was reading it from the OBD port. That means nothing on the JWT kit because the MAF AIT sensor is right at the air filter at the front of the car. I now have my Haltech reading air temps at the plenum neck. Temps are about 30 degrees hotter on average (than before, which was more of an ambient temp reading).

Next time I dyno, I'm going to be data logging (now that I know how). For all Haltech users, learn to use the data logger. It is pretty neat stuff. I would love to see data overlaid onto a dyno curve.

 

I think you are right, its in from the OBD port, which is fine for all but JWT. When I get retuned by Sharif, I am definitely running a few logs on my laptop on the dyno. That way I can compare if something changes from the day of the tune.

 

congrats on ur build OP.. a couple of years ago people thought this was impossible. gives me hope that i dont have to buy another turbo kit and be out 7600$ for a kit alone.
