Hi all I just got tuned at national speed in nc. The video is up on there facebook page under nicks evo x .
Mods: hks panel, hard upper pipe, invidia catback, grim 3 port, gfb bov, and trq short shifter.
2011 gsr 93oct
Base run with all mods no tune was:
289 hp 302 tq

After tune:
337 hp 320 tq


Dyno was a dynojet.

Now cobb app warning.
I had the app early 2010 did the beta tunes but because of knock unmarried it and sold it no other tunes were done.
While at national speed they saw in the first run that the boost would spike then drop then come back up to normal level then fall hard.
He looked at the boost table and the number were all messed up so when the cobb app unmarried it must not have copied the stock tune correctly or it scrambled the code.
So if you use the cobb app and go back stock it might not go back all correct granted this is one case and not all might be the same still good idea to have a protune or have some one look at the tables to make sure they are good.
But if you want to go stock best to unmarry it then take it to the dealer for a stock reflash.

I will post picks of the dynojet sheet soon but if you watch the video it is shown at the end.

Thanks guys

Video from the dyno

 

I forgot the boost was set at 23 psi and afr's stay in the 12-11 range the whole rev range.
We tuned it this way so it would have 0 knock and would be use able In most any condition for when I go to Korea.
They did a great job super friendly and won't do you wrong.
They also did a boost leak test before the tune on request for no extra charge I love this shop.

Thanks to them the car feels so strong and with the short shift feels like a new car.

 

Hi all.
The dyno sheet is up now.

Blue is the base line
Red is the final after tune

You can see on the blue boost curve where the stock tune was not copied right from the cob app good thing it's all fixed now thanks to the guy's at national speed.

 

did you remove the pill while you were using the beta maps? and did you put it back when you went back to stock?

 

I took the pill out when I was on the app. But when I went back stock I replaced the hose I took the boost pill out of with a new factory because it ripped when I tried to put the pill back in.
But when it rewrote the stock tune the boost tables were not put back correct.

I did not know till I got a gauge then I was the spike drop then back up. I thought some thing was wrong when the gauge was showing 25-26 psi on the factory tune.

But every thing is fixed now thanks to the tune so just wanted to put it out that the apps might not copy your stock tunes fully.

Just some thing to watch out for.
