I have recently purchased a Manual G87, first service is yet to be done at 2000km and I am thinking of tuning it to stage 2.
I live India and a team is ready to tune it. They have tuned almost every cars and bikes available in the market I just need more recommendations as it's my first time.

So what performance parts can I use? As it's a manual.
Is 10K km enough to tune it or should I wait for longer period of time and use.
I use 98 octane and it's not an issue.
Mileage will be affected a lot?? As I use it for long drives as well

What will happen to my stock parts, in case I want to use in the future is it possible?

I am okay to add completely new performance parts so I don't have to do anything with the stock parts.

Are there specific parts just for a Manual?

I am somewhat aware of what happens in a Stage 2 tune but no one has done it in India so kinda worried. Please help out patiently 🙏🏼

💯✌🏼

10K to tune is more than enough, I would do it at 1K

I cant answer the mileage question it depends on your tune

Im not sure what you mean by what would happen to your stock parts. If you want to use them again, then keep them. if not you can sell them or toss them.

except for transmission parts, everything else is shared with the auto model

As stated, no limitation on mileage (I tuned mine at 2,000 miles).

You will obviously need to send your ECU to femto to unlock it. If you are using true 98 octane, you will need the tune customized for that octane.

For a true stage 2 tune, which should get you about 625 - 650whp, I would recommend the following aftermarket parts: heat exchanger, oil cooler, catback exhaust (with valve controller), either highflow catted (200 cell) or catless downpipes, either BMC drop in filter or true upgraded intake such as Eventuri (I don't think AWE has an intake released yet), heat range colder plugs. I would also get a skid plate installed (I like the Mishimoto). You could also upgrade the charge pipes (hot and cold side).

You will need some wider meat on the back (tires).

What do you do with your stock parts, save them if you have the storage or to the dumpster.

I have a manual G87 that is stage 2. My tuner was concerned about the stock clutch in the manuals. Their opinion was the are good to about 550 WTQ. That was the biggest limiting factor for me since I didn't upgrade the clutch. Having put a couple thousand miles on it post tune. The OEM clutch seems to be able to take 550WTQ.

550 wtq is what I have seen most tuners use as their ceiling for a reliable manual. im sure it can take more but tuners prefer to keep it under that limit for the best reliable daily driver.

I can appreciate that. No one likes being stranded.

Someone should get RPS or some other reputable clutch vendor to make a proper multidisk carbon on carbon clutch. The spec triple disk in my f80 was absolute trash.

They are out there. The M4 forum found one that works good for 800+. I did a little digging before I tuned my car to make sure I had a back up option if I blew mine up.

What’s your opinion on tuning with stage 2 knowing only ACN91 is available? Would a stage 2 hurt value if eventually trading up for a new car and selling back to dealership?

I really hate 91oct. I've got the same problem. CO's 91oct isn't quite as bad as CA's but add in the 6,800ft and it's tough to get Stg2 happy. Stg1 no prob, DPs and 91oct much tougher. For piggybacks/BMWs anyway.
I'm sure a full unlock with good dyno time / tune would be fine.

Same on my f80 the aftermarket clutch options really ruined the daily driving aspect for me. None had that stock feeling.

Are you saying piggybacks have trouble with CO’s 91 and elevation?

At Stg 2, possibly. Map1 (Stg 1) on JB4 should be fine, but pushing the tune to a OTS piggyback Stg 2 with new downpipes + 91oct, things can get dicey. I and others have experienced this and the only real solution was a full ECU tune solution. I had to run octane boosters and stupid stuff and never got things 100%. I asked BMS about map 2 on 91 and it was a no-go. They said they’d have to do quite a bit of logging with me and couldn’t guarantee the results on a real Stg 2 on 91 oct.

Ah okay thanks, appreciate the feedback!

Is the clutch the only limiting factor or are there concerns with the entire transmission being able to hold up? I really haven’t seen many issues with tuned manuals on forums,etc. at all.

From what I have read and talking to my tuner it is only the clutch. Everything else can take the torque.
