Just did some tuning on the boss's completely stock 4k mile MR. We're both really happy with the results and will be working at getting some bolt-on's installed, tested, and tuned in the very near future.

Here's the best it would muster on the stock tune. Most pulls were in the 240's, but it did put down 250hp twice... So the best pull it made completely stock:


Here's after the tune:


And of course, the two graphs overlayed:

 

nice gains, hows the car feel now?

 

Damn 28psi! Nice gains.

 

Actually, its only showing 24~25psi on EvoScan... So I do believe there is some discrepancy between the two... I dont know which is closer to accurate, but Im also showin zero knock counts

 

I was about to say that is a hell of a lot of boost. Great gains, the car must feel much better now.

 

It does indeed... Like an entirely new car, lol!

 

Why was the car only boosting 18psi stock for the baseline?

 

I believe there's something wrong with the Dyno's boost gauge. My datalogs are showing a peak of 20~22psi on the baselines, and 24~25psi on the tuned pulls. I wasnt sure which was more accurate... Untill I realized that the dyno was reading low on the baselines and high on the day I was tuning.

 

wow thats funny.... after many bolt ons in my 370z I was able to muster just about as much power as you guys got in a few hours for a few dollars, lol

the turbo world is too easy...

 

Actually for us, there were no dollars... Well besides my paycheck Since we own the dyno and all

 

Hahaha! I remember when I had my 06 350z.. I dropped like 4grand in bolt ons and got like 10whp! I'm kidding, it was a litle more than that, but you get the idea.

 

Yep i had a 03 350z with full bolt ons and cams and barely hit 300whp

 

We had a 03 come through here for some pulls recently... Catback and cat-delete, and an intake... 258rwhp, 248 rwtq

 

Justin, What kind of pressure sensor is on your dyno? We have the GM 4 bar and I know its correct over every other boost gauge.

 

Forgive me if I am wrong but the tune still seems excessively rich, couldn't you lean it up a bit?
