From watching my two buddy's dyno pulls with their Z's, they all shut down at around 7500 rpm.
You can raise the rev limiter, we don't suggest it. More so on the VHR motors. You don't just buy parts from the corner store to rebuild those heads. Nissan only sells the heads as a complete assembly and they are way out of line considering what the retail on the entire car is.

If you want to raise the rev limit to gain more power on the VQ motors, just do yourself the favor and have cash available to rebuild the motor when it grenades. As long as you understand that, the VHR motor makes power till well over 8k rpm.

Hey Sharif...Are you talking about my tune being the next highest? I want numbers like SEMTEX!!! We basically have the same setup in terms of bolt ons, etc. Why the big difference? Just giving you a hard time, but I'm curious. Is it because he has a Blue Z???

For those reading this thread...below is my chart from Forged.

Does anyone know if these are SAE corrected numbers?

Good to see some results finally. Its going to be hard to justify spending $1100 to get the software and dyno tune for 6HP though....

Curious to see the results of a e-tune compared to the dyno tune.

I forgot to mention the lower number was before the UpRev Reflash and the higher number was after.

You posted the same graph twice. Both are AF. I think you meant to post the first one as the one showing hp and torque, right?

My thoughts are . . . ugh . . I'm speechless right now. I'm about to post some updated info in a few mins to this thread. You'll see why I'm speechless.

Default Problems

Okay folks, all is not well. Two things are going on.

First, since getting the tune done, my car is doing something rather strange on cold starts. I start the car, wait my normal 30 seconds for everything to warm up, and when I slip it into 1st and tip the throttle in, there's like this weird dead spot. Gas pedal goes down a little, I start to feather the clutch in (same thing I've done a million times before), and nothing. The rpms just kinda don't go up, then all of a sudden, WHAM, the rpms jump up to where they ought to be and I go lurching forward like I've never driven stick before. But it only happens on cold starts, and goes away as soon as the car has warmed up a little more. Like by the time I get out of my neighborhood and make it to the first set of lights a half-mile from my subdivision, the problem is gone. I can launch as smoothly as always. No dead spot, no lag effect.

The first time this happened was yesterday morning when I left to go to the gym. I thought maybe it was my imagination or maybe it was human error on my part. But this morning, it did the same thing. It even did it when I was done with my workout and left the gym to come back home (car sat for about 2 hours). Something is f'd up. The driveability of my car has been compromised.

Okay, the second thing going on is this. I just got back from my DynoJet pulls. I have LOST approx. 15whp since my last DynoJet pull on the same DynoJet! Check it out. RunFiles 003 and 005 below are from today. RunFile 010 is from back in May.



I know, I know . . . different pulls on different days, months apart, right? But look at the run conditions:



The green and yellow lines are from today. The blue one is from May. It was cooler today than it was in May. Humidity is higher today than in May, but the correction factors should compensate for that.

Take these two things together -- the weird dead spot on cold start, plus the bizarre dyno results, and I think I'm being fair in saying that something ain't right!

I haven't been able to talk to Sharif yet, so I'm not sure what the next steps are. But right now, I'm about ready to have him flash my stock tune back in. This is not the desired result.

One of the things that my Uprev tuner did was to give me five different maps controlled by the cruise control buttons: performance, economy, stock, valet, and theft. It is pretty easy to determine if there is a problem with the tune.
