i see this option is available with UPREV but im not sure what is meant by this. Can anyone give a quick explanation? Some of the Dual CAI kits have 3" diameter tubing, is this what requires something extra when tuning with UPREV?

 

Give us some background on your car...

what are your goals for the car (power / torque)?
what do you want to do with the car after the modifications / tune?
how much money do you have to spend on this?
do you already have an Uprev license?

what year is your car?
what transmission?
what modifications do you have on the car?
what modifications do you intend to do in the future?

 

I have a 08 350z enthusiast, 6mt, 13,000 mi that is all stock. I would like to do a cat back, cai, and tune. My goals are to please my ears as well as my butt dyno. I am not concerned with dyno numbers. I do want to keep the car's drivability and reliability. I would love to put a SC on the car but the wife won't have it.

 

Any time you make induction/exhaust changes, it's always good to have the tune match the "improvements" - corrected A/FR - but is it worth the cost of the license and tune expertise to get the most out of the mods on an otherwise stock vehicle? Only you can decide that. It's a pretty hefty price/hp ratio.

 

Uprev would be a good solution for you and your goals. Don't worry too much about dyno numbers but go and dyno tune (as opposed to road tuning or E-Tuning). This will ensure a safe AFR, safe ignition, and a drivable car.

I would do all your modification first and then go tune.

 

I agree,but I don't think there are any tuners with a dyno near me (Western PA). I was thinking that there would be plenty of existing tunes based on similar mods that I could use?

 

Its your car and your decision and your situation. A e-tune may be your only solution. It wont fully optimize your setup and you may not recognize 100% of the potential gains - but that's the downside of not living near a tuner/dyno shop I guess?

 

bealljk, could I ask you for some information on exhaust sys. I know its been dicussed to death, but i would like some first hand answers.

 

IMHO $300 for CAI, $500 for UpRev tune = $800 for mb 8 HP isn't worth it.

 

Very few things in the automotive aftermarket are "worth it" but to modify the basics on the Z, thats the price you pay.

 

ask away...

not when, for $2500 to $3500, you can go FI and gain 100hp to 150hp

gotta pay to play!!

 

Exhaust? Stillen, Nismo R-tune or HKS, have you heard either of these in person? I do not want anything annoyingly loud. Also don't want to get a headache driving on the freeway in 6th gear.

Forced Induction for $2500 to $3000? Please tell me how!!!

 

Hey my friend, simply saying Nissan did a great job with stock air boxes. CAI really doesn't improve a VQ35. When I got mine, I measured temp difference with a laser thermometer. 6 degrees. Plus the OG is polycarbonate, aftermarket is metal, so heat soak...

 

I'll echo what JHC said with regards to the OEM intake. The reason we know this is true is that no one, after 15years, has made a better intake. And furthermore you need a tune to recognize those gains. I wish some would re-tune a completely OEM car to see if there are power gains just from a tune?

Havent heard a nismo nor a HKS but I ran a stillen for a few years. Best thing about the stillen is that it has a quiet rumble (ie neighbor friendly) for lower RPMs but will open-up and give a pretty nice 'broughpy-bubbly' exhaust note on high RPMs ... one downside, it's heavy ... when I went weight-savings single aluminum I dropped 40 or 50lbs compared to the stillen.

Yea, I fabricate rear-mount turbo systems with a buddy - if you're interested feel free to PM me.

 

I have the HKS twin and love it but it's a LOT of money for an exhaust, you can get Beall's turbo kit for that much lol.

 

Are you referring to the True Dual system? What makes it so expensive?

 

Yes, all 3 of their systems are true dual. I believe the price goes from hi-power to twin muffler to sound master. The hi-power is the cheapest and loudest I have the middle one. Hi-power goes for around $1500, mine about $3000 and I have no idea how much the other is.
What makes them expensive? It's HKS, basically Gucci lol. Their quality is impeccable but it is overpriced IMO.

 

Oh no wait, apparently I have the top dog, you can have the Gemini which is similar for a fraction of the cost. I got mine because of quality, looks and sound. That and nobody has it, I have this "rare" factor going on lol.

I have one, but unsure if my RevUp 06 would be relevant to an 04 or 08?

Mase/Stage6 is like, 10 miles away. IF it is, I'll take one for the team.
