Their is no easy way to know 100% unless to read the rom from the ecu and compare it to stock.

If you cannot read the rom from ecu then that may also indicate its tuned as some tuning systems ecutek and brzedit disable read.
You will also need a device to read ecu , or access to someone who has one

Some tunes have distinct features some do not.

Correct me if I am wrong but stock tune does that shit and feels like car is going to stall by itself.

Nope not a good indicator. Mine idles at 600 and is solid as a rock with no tune.

Which is a very real possibility, especially given the shit I see owners post on Facebook....

Hey jsimmon7777 I'm in Fairfield. I just tried to see if I have ecutek and nothing happens with the cruise control. 1st gear Rev and let's me go past 6k so pretty solid evidence I don't have a tune. Which makes me happy in the sense I can get more power

Even if the torque dip was gone I would still feel it if my other car was an E55 amg.

Yea she's kinda slow too

Well, you're not going to gain much from a tune unless you get a header and/or run e85. Also, to save you some searching:
+35 9" wide wheels on stock suspension
+45 with camber and coilovers
yes, RPF1 are still the standard
the car actually understeers at the limit stock until you put down the accelerator
yes, you need an oil cooler to go to the track
yes, you need track brake pads front and rear. Most people go project mu. I am one of the few who like PFC 08.
yes, you need to replace the brake fluid with something higher temp. I like ATE.
No, those coilovers are crap, and that anti-rollbar probably is too
Yes, you want front crash or camber bolts - you'll get about -2 degrees, which is enough for most people
You can adjust the clutch downwards. You can remove the spring. I'll be replacing the cylinder with a smaller one.
SBD makes the cheap turbo. Full Blown makes the drag turbo. PTuning makes the track turbo. Jackson makes the track supercharger.
OFT does pretty much everything that EcuTek does and has a screen for real-time data. It's also not beloved by many tuners who want to lock up their tunes.
The thread about helping the guy find yoga pants for his girlfriend is really just an excuse to post pictures of scantily clad women.

There, now you can leave the forum now. Though you might want to check out the yoga pants thread before you leave.

Lol well thanks for the information overload. I don't really plan on tracking this car but wouldn't mind having her ready to do so. This is how she sits now, I think I'll stay around the forum for awhile. T

Everything you said above is pretty good info except in red.

OFT is not a proper way of tuning if going FI and/or E85. Custom Ecutek maps are required to properly tune an FI 86 and flexfuel for E85.

So I can't buy a turbo kit and get it tuned for 93 pump only with OFT ?

You can get it tuned, yes.

I am talking about doing things right, having the proper safeguards in place etc....

With Ecutek you get electronic boost control with CC stalk, you get overboost protection with several parameters, you can input a real wideband into the ECU to be able to properly tune the A/F ratio of the car, different timing/gas maps for different situations, Speed Density for when your MAF is no longer able to provide you a window for tuning because it's maxxed out, etc.

You can get turbo/supercharger kits tuned with oft, but its limited to the specific kits offered by either the OFT guys or the Speed By Design guys (SBD).

Other tuners are reluctant to use opensource as their work can be copyed.

you will find that the oft and sdb kits are limited to about 10psi boost as after that you start to need some of the fancy add on features of ecutek software like boost cut, flex fuel, hybrid speed density ect.

However see here ztan has already implemented overboost cut and speed density patches for opensource. Shiv/OFT is now using the overboost cut patch on their OFT 350 turbo kit.

In the not too distant future opensource flex fuel may be done and the gap between opensource and ecutek will be much less.

Their is already a guy in australia "throttle happy tuning" who has flex fuel running without ecutek, its not open source though he uses brzedit and has written his own flex fuel code for 86/brz

although you will still run into the problem of many tuners preferring to use ecutek due locking of tunes and that they dont have to manually patch roms ect, ecutek software does it for them.

The biggest hinderance to FI with OFT is that when you go FI you generally want a proper dyno tune and those guys won't touch OFT if it doesn't let them lock the tune.
