As you may know our car utilizes a Drive By Wire throttle. The throttle plate only opens a 70% when the gas pedal is floored not your usual 100%. I'm sure you've noticed the slight delay when you floored it.
According to the throttle tables, when you're pedal position is on 86% you're throttle plate is only opening at 52%. I'm not sure if there is a good reason why nissan did this.

^ Overheating issues => Limp mode?
More fuel burnt = more heat released
More fuel burnt = more heat released

I would love to try and open it up to at least 90% especially with upgraded intakes those should make quite a decent difference.

My car needs to be serviced soon. Maybe I can try it out on the loaner car and see how it goes, hmmm...

the throttle tables are pretty ****ty to begin with, at %56 percent foot throttle the butterfly are only open like 20% ..its pretty bad. BUT the full throttle limit is %87 and thats because the difference between 80-100% throttle is 1% power difference, but keeping the throttle slightly closed causes better atomization and emissions.

actually if you want to get even more technical... an NA internal combustion motor pretty much works the same throughout the entire spectrum.
You want it slightly richer at peak torque, then lean at peak hp.
EX: 12.7:1 to peak torque, and 13.0:1 at peak hp.
I've built a few 800hp+ motors before, na and FI. FI obviously you want to go way richer.

yes its adjustable with the cobb ap, yes all modern cars have this limiter, pretty much anything that is drive by wire has these limitations, some way worse than others, all for safety and emissions reasons. the G is programmed to only allow 25% throttle until after 3k rpms, so that if your slowly rolling you dont spin out of control. all the limitations on the car are to make it very driver friendly so your grandma doesnt spin out into a tree. this causes a very unresponsive car when we are trying to push the ***** out of it.

Here ya go
"I have a g37S 5peed automatic.
Fi cat back/fI H.F.C.'S/Stillen stage 3.
I had cobb installed with stage 2 map, but for some reason the car responded much better with the stock map.
1st pull 310WHP.
2nd pull 305WHP.
3RD PULL 308WHP.
AFTER REMOVING COBB STAGE 2 & REINSTALLING BACK TO STOCK MAP.
1ST PULL 318WHP
2ND PULL 315WHP.
3RD PULL 325WHP. "
