Why is that Dyno Jet numbers always seem to come out higher.

 

Holy shiet... 312 hp from just hfc and intake?!?! 07+ sedans only go up to 290 something with the reflash... so far with mild tune.

Hopefully, they'll tune it closer to 300hp on our sedans as well.

 

So we are only looking at a 22 or so HP difference. But the A/F ratio is better and the Torque is more smoothed out. Along with total gains on the HP not, low on the mid and high in the high RPM or what ever... it is all smoothed out.

 

It was the NA model.

 

I wonder if the new model they made for the G37 will be more effective?

 

How much was the tune?

 

see it did take deciphering

 

so you got 22 hp with a ECU retune and Intake and HFC and Exhaust? or 22hp on top of the gains from HFC intake and catback?

 

How long did it take? And yea, were you the first for testing or did you have to pay?

Yeah the max gains aren't really seen, but the graph as a whole is a lot better. With the tuning the there are no ups and downs... just ups. And the Throttle response is A LOT better. Even with TDC on.

 

It took 2 weeks to send the ECU to JAPAN, then 3 weeks to finally figure out what Nissan did to screw us over and make it harder to tune.

I was the first to tune so it was free to me, but I think it is about $550 to $600.

 

If you have the same options as me it should be a 2 day turn around, if not less.

 

ok... let me ask again... +22hp gain wwas the best run right? with intake,ECU, HFCs, and Exhaust ?

and it was dynoed that HFCs and Exhaust and grounding kit made +22 hp also...

I think im missing something here? or what?

 

I know the numbers don't add up right. The plus 22 wasn't off the best pull it was off the third pull. The real question is on what pulls did the IT article take the readings. At Tsquare they did it after the car was warmed up not with a cold engine. I think I read before how someone did three pulls and the numbers were different there. I think they said the results got worse.

 

yea i dont understand it either... one day we will figure it out...lol
