[Official] "Do I need a tune with bolt-ons?" thread

Footloose301 · 04-30-2011, 01:46 PM

I'm running Stillen Gen3, HKS Hi Power TI exhaust, and GTM Resonated test pipes without issues so far..... :-/

I desperately want a tune but at $600... I wanted to wait for pulleys first.

Yeah the only thing holding me back right now is the price of a tune. It sounds like it would be beneficial for what I have on the car, and would even be more worth it if it's "hurting" the car in any way without the tune.

from the reading uprev seems like a good choice. plus no real hardware to get, just an OBD2 adapter to USB cable they supply in the purchase.

im more interested in getting rid of the throttle lag at the moment...

If I were you I'd just hold out till you get some test pipes/ HFC's and then get a tune at the same time. Your probably more than safe now. Before my tune and all three of my breather mods I was lean but not dangerous lean. Are cars compensate pretty well.

Hey all, I just wanted to find out if I will need to up rev/tune my Z after adding some bolt-ons. I have a Gen3 intake and FI TDX CBE is on the way, I just want to find out if I will need to do anything after/when I get these mods installed ?

Ok so I just bought an 09 370z Saturday. Being the kind of guy I am, F.I. exhaust and stillen G3 intake are in the mail. I had an 06 mustang GT before this, which had a great community of tuners that sent reflash files for those of us too dumb to know where the dyno guys were at. Quick plug into the obd2 with the sctsf3 after any bolt on mods and you were set. however, I feel the Z is a much more luxurious vehicle and will receive special attention. I have never done a dyno tune before, So do I NEEd to get one? will I ruin anything with these 2 minor bolt-ons without a tune? I MIGHT put HFC's on later, but this is probably the extent of my engine modifications. I'm just new to this whole thing and am looking for advice. I live in college station TX, so if there is anyone around here yall know about that would be great information to have. Thanks for taking the time to read this and I appreciate any advice, I'm new to the Z world haha.

I have the F.I. exhaust and G3 intake, but never got it tuned afterwards. It has been at least 6 months and I haven't seen a need for a tune.

gbrettin · 05-21-2012, 03:26 PM

I have the F.I. Exaust w/o a tune and haven't had any issues. I've been driving this way for about 1.5 years.

Pelican170 · 05-21-2012, 03:35 PM

You dont need to get it tuned as the ECU will correct itself with some time. Although a tune is recommended to get the A/F ratio perfect...

bigdog1250 · 05-21-2012, 04:25 PM

You definitely don't NEED a tune. That being said, a tune will help get every bit of power out of your mods, just wait until you're done putting on bolt-ons to do it.

Congrats on your new Z, you're going to love it.

P.S. FI exhaust is the best! Good choice

Huck · 05-21-2012, 04:33 PM

G3's and just the CBE won't affect your A/F ratio too much to where you NEED a tune. I've got the G3's, and my non res'd FI LTH/CBE combo will be here in June. I'll be getting the Uprev after that since that freeflowing of a design is a little bit more dangerous...

MacLean · 05-21-2012, 05:03 PM

Welcome & congrats on ur Z purchase along with ordering your mods.

Vichtz · 05-21-2012, 05:49 PM

Thanks for all the advice and quick responses. The car is great so far. I'm not gonna say i don't miss the pull the 'stang had off the line, but the high-end pulls in the Z are to die for! So I don't need a tune but it would help milk the power. I have never done anything like this, who do I talk to after I get the parts installed? I can easily make it up to houston or stop by austin on my way to san antonio, so what are the best places to go between the 2? Obviously this is for the TX people haha.

DJ-of-E · 05-21-2012, 07:08 PM

Funny how he's probably a first to go from Mustang to a Z and not vice versa.

Nick911sc · 05-21-2012, 07:12 PM

Just wanted to let you know, as I hadn't seen anyone else say it.

As stated the G3's and CBE will be fine without a tune. But if you add HFC's you will need a tune to be on the safe side. The car could possibly run too lean with the 3 breather mods combined.
