I had my Z dyno-tuned a couple of months back. I had already flashed it with a "base-tune" before heading to the shop (I purchased Osiris standard here in the Marketplace).



2005 350Z Performance (~39K miles)
5/16" Copper Iso Thermal plenum spacer
M2 Performance catback exhaust w/Magnaflow x-pipe
ERZ HFCs
UR stock size light weight crank pulley
Drop-in panel filter
91 octane

I'm very happy with the results. Feels like a different car. I once again find myself taking the long way home just to get more seat time.

 

very nice. That's a significant gain in every aspect.

 

Very nice gains!!! I bet that thang rips now!!

 

Whats results before and after? On my phone cant see the pik clear

 

From: 243.5lbft / 252hp
to: 255.4lbft / 269.4hp
Gain : 11.9lbft / 17.4hp

 

wow those are very nice results I must say, looks like the runs stopped after about 6600 rpms, did you consider the rpm increase by any chance ? I'm just wondering if it would be worth it through the 1st few gears. I would need to determine by checking power band if you would still land in good spot when up shifting

 

Im pretty sure most on the forum will agree there's no reason to take it past stock redline bc there's no additional power made without internal work

 

I didn't have any specific instructions for the tuner; I just let him do his thing. All I wanted was a optimized and safe tune.

 

Whats your low end at? I have an 05 and going to do same mods. But i want a good low-mid end. Without sc or turbo.

 

Mods to meet your goal:
-Cold Air Intake or at the very least a K&N Drop-in filter.
-Motordyne MREV 2 lower plenum (only if your engine is RevUp)
-Motordyne 5/16th spacer
-Motordyne Art Pipes or high flow cats if emission inspection is required.
-Z1 Motorsports Headers (formally known as Momentum Headers)
-Whatever free flowing exhaust you like the most. This tends to be a preference thing especially when it comes to sound.
-Uprev tune after all Mods are installed by one of the tuners that's highly recommended here in the forums. ***WARNING*** Just because they are on the Uprev site as certified Tuner doesn't mean that they actually Tune properly as some have found out the hard way with blown engine... Yes even N/A.

By the way... Talk about grave digging...LOL

 

what would be the effect of installing a MREV2? would I need to re-tune right away?

 

no.
