So I have my Z running and its been driving well. I have Nistune controlling 420cc injectors. My mod list is below. I hope to be running about 15-20psi.
So i have a base tune so far with 376 K constant and 76 as the latency. The car runs well and boosts safe. I think there's a lean spot since it does pull sometimes more than others.
I plan on getting it tunes at http://enhancedstreetperformance.com/ in my hometown. IT would be tuned by there nissan tech guy. It's 175 an hour and the guy there said it could take 2-3 hours. My bothers 240 was tuned in a hour. I'm wonder how worth it is getting tuned professionally and how much it can help power-wise from say a "homemade" tune. Since it could potentially cost me 350-400 dollars.

I think you should, but only based on the fact that when I do get Nistune i'll be needing to take my car to a shop somewhere in MA and right now I don't know of any places that know it. I don't want to waste money while someone 'learns'. I don't know enough of the benefits to a professional tune vs. what you have done already so I can't give an opinion on that. Although I am guessing they will be able to get you more power out of your current setup after an hour or two. -
how is the pro products FPR treating you? I think we have the same on.
Mine tends to leak where the fittings go in, but I may just have them a tad too loose? -
Yes i had a lot of trouble with it leaking through the threads. Finally found a gas resistant sealant. Some special order loctite.Careless wrote: how is the pro products FPR treating you? I think we have the same on.

Anyways. Back to the thread… -
Find out if its a load bearing dyno or a inertia dyno, ideally a load bearing can be more useful for tuning
you should expect most experienced tuners for Nissan will be from a 240sx background, it would be good to ask about NisTune experience -
Has the guy used nistune before? If not see if he can cut you a deal on the price since he is going to be learning how to use the software. -

There website praises their load-bearing dyno.
But I'm asking the effect on the car. What can be unleashed vs a homemade tune. -
Depending on how good your current tune is you can "unleash" a lot of HP especially on the dyno where you can effectively set timing and boost to where it's efficient.Usual Z31 suspect: Garage Queen (aka broken)

I know the guys there and the guys there know me, who exactly is their Nissan guy who is tuning?
is the Apex'i TCBOV vented directly to atmosphere, that can cause a stall/lag effect in between gears when still using the MAF.
also only people I know that does Nistune and first hand experience with it:

They have an AWD mustang Dyno (the brand). It is a load dyno and you need to know the actual weight of your car with you in it to give you the correct numbers. You need to weigh it at the scale with you in it. Worcester has a public scale on Southbridge street.NissanXRMA wrote: There website praises their load-bearing dyno.

a homemade tune you can't see the torque gains from adding or removing timing which translates to more power. on that dyno you can do steady state tuning which you cant do on the road.
For BMW's, Porsche, Audi, MB and other cars a tune starts at $900 + the dyno session. $400 is very reasonable.Gone - 1988 Shiro

Not sure who their guy is.
I run a blow through with the MAF/BOV
Danbury if quite far though. :-? -
I'm not sure what the difference is between your own tune and paying someone to tune it???
I thought that Nistune had map trace for the purpose of tuning?
You could do a couple of tunes your self get a average, and take it to a dyno and see and make adjustments from there.88na2T-s13,q45 swap 12.6@110mph

Good luck next time bro. That's why you do your research on tuners first lol.Originally posted by DMANN
And you pay someone to tune it on a dyno for the reasons all above. Mostly because you can tune into max power without blowing it up better than on the street with a butt dyno. Keep upping the boost or timing and see what happens on the street versus seeing power to start decreasing on the dyno telling you when to stop.Usual Z31 suspect: Garage Queen (aka broken)
