yay another chance to get Defi Gauges is another chance to make me happy in the pantaloons.

so far as the header issue goes, is it possible to alter the CVTC controls in the tune in order to reduce the valve overlap so those who run headers can get their 2 psi back? or are we still waiting for a tuning company to figure that out?

^ Still waiting.

CALM DOWN ABOUT THE DAMNED HEADERS!!! LMAO!!!

I think I scared you guy's a bit and I apologize! I'm only reporting what we've seen in the past...Keep in mind that when we install long tube headers on a Nissan Titan, there is no drop in boost, it runs a bit lean but we correct that with our tune.

If you have header's on your vehicle I would not worry about coming up with a solution today because it might not be necessary. Let us test it for you and see what we come up with.

How happy would you be if I told you the headers gained more horsepower and were a huge benefit?! LOL

I hope no one takes offense to my last post...I just think I got people worked up about the header's more than necessary and that was my mistake.

^ It was warranted, its getting ridic. Just tell them their cars will blow up with headers. Just immediate explosion when you turn the key. I mean the entire car. Oh and the color blue will cease to exist.

LOL!!!

My post was really just meant as a joke but after I wrote it I remembered that the member's of this forum aren't familiar with my posting style yet. On some of the other forum's I visit I have been a member for four or five years so they're used to me joking around...

You never know the tone of someone's words on the internet so I just wanted everyone to understand that it was a joke and I wasn't just trying to be a jerk.

Ya your a **** Kyle lol.... Seriously though.. you do have me a bit worried.... I have everything Stillen except for the Cats and I am scared to drive my car now cause it pretty much sounds to me like the worlds gonna end when I start driving the piss out of my car, which is the only way I know. Tell me that this isn't true and I'll be good to go!

It looks like you've done a great job so far but you are correct...Your car is on the verge of melting down so I would recommend a few things...

#1) STILLEN engine oil cooler kit...This will keep your oil cool and prolong the inevitable melt down.
#2) AP Racing big brake kit front and rear...This will allow you stop much shorter when your car bursts into a giant ball of flames as you travel down the freeway!
#3) AP Racing brake fluid...The boiling temperature is higher than standard fluid so when everything IS on fire...you're fluid will be better suited to perform with the AP brakes and get you out of the car faster!!!
#4) STILLEN sway bars...Again, when the car bursts into flames you want to make sure that you can make quick turns to immediately exit to the side of the road...This will make your car handle better.
#5) STILLEN urethane bushings...They handle the heat from the flames much better than the factory rubber bushings will!

All of those things will seriously help you out when you try to drive your car spiritedly!

Seriously though, you're setup is perfectly safe. I wouldn't install the high flow cats just yet because it will be on the lean side and outside the range of what we would consider "safe." We are working on a tuner that will give you a safe a/f and improve your power as well. If we can stick with our current path it will be a very affordably priced option! Let us work on the tuning for you and you'll be ready to rock all four in no time!

There is a simple solution if u have header/hfc or LTH... Go to a tuning shop and get your AFR adjusted. Thats what im doing when A. i get my nitrous set up finished and B. when i get my exhaust mods. I dont understand why people are making such a big deal about this.

Do a lot of shops have enough experience and skill with reflashing the VQ37's ECU with an aftermarket forced induction system?

Gotta start somewheres. No offence to Stillen or any other vendors. But whats the difference in stillen sending you a canned tune that isnt made for your car specifically and a tuner shop that hasnt done much or any work on the VQ37 with a FI setup?

I'm heading to a local shop when i come back from my operation with the army to get a tune for my nitrous set up. They never worked on the VQ37 and agree'd to give me a huge discount.

Personally i think its alot safer to go with a shop that hasnt had much expeirence then a shop that has but gives u a base tune that isnt set for car specifically. Yes its a 370z but all cars are different. My buddy that had a tune on his cobalt was perfect for his car but even with the same identical mods as him the tune wasnt good on my car. Once again im not bashing stillen or any one, just stating my opinion on the topic.

glad you brought this up... for the occasional casual track day, I sure would like to be able to run 91... any way you guys could include a switch? even if this was introduced as an upgrade at a later date, it'd be appreciated

also, any more details you can share about the race-oriented version? you are assuming full a/c delete right ? anything else we should know about how it will be configured and what kind of differences we can expect from the other versions in terms of power gains, lag or whatever ?

thanks

i wasn't exagerating i said 2-psi which from experience is what i've seen. granted that was on cars running 14-20 lbs, and it ges down with less so maybe one psi. But the point remains valid will you have the ability to tune the CVTC to remove the valve overlap that robs boost from header equiped cars? It isn't the effiecent exhaust that reduces boost it's the valve timing. J/W because one of the main points of this car is it's ability to customize the cam settings in the ecu.

it really sucks to know that i shoudlve held up on the headers... sucks donkey butt... in for updates though...!!!
