How are the older B48 engines holding up that have been tuned? I have not heard of any major issues.

I used to have an X2 m35i with that engine. It would hit 22.8psi stock.

Your telling me for $199 the TT I would have got similar results ?! I'm kind of bummed.

Then again Bootmod3 is a full tuning platform, TT is just a piggyback

Good thing about BM3 is that you can customize literally everything and piggybacks are just modern day boost controllers

Any updates on the car? I think I'm doing +6 psi with Map 3 on JB4 with a E30 mix but I haven't gotten to dyno it yet...

Is the car doing alright? Any weird issues to look out for?

Look at the previous-gen N20 and tunning, very rarely have they let go and there are millions of them out there.

With that said, you always run the additional risk of failure when tuning your car, whatever component that is - nothing is 100% fail-proof.

On a side note. Here is my 0-60 run with this exact setup and 275 Mih PS4 using coded launch control.

Wow. I have the same setup , could you update me on what exact settings you were running in TT such as base and slope. Also did you ever try turning boost to 4 for faster times?
