M140i is lighter by only 70 Kgs than 340i, also he's using 100 RON which is a bit more than 93 US.

I think 6s would be possible if it wasn't for the xdrive.

M140 and 340 with same setup 140 is faster end of story, same thing is rwd agains awd from 50-60.Problem in my country is that roads is very old and with my previous 335i bm3 st2 most of the time i make 0-100 8sec 100-200 9.6 literally no traction till 120-30kph Thats why i decide to go with xdrive

[IMS-340C]

No doubt M140i is faster but not by much, I would say one car length 100-200.

Yeah no traction here in my country too sometimes I get wheel spin when flooring it at 140 Km/h it’s crazy and that’s on MPPSK tune.

Its starting to sound good!

Who else installed the VTT GS turbine and tuned in, are there any? Write the results, at least some boost at 6700rpm and acceleration 100/200

Mine make 491 whp on mustang dyno on 100ron tuned by Paul Johnson.11.06 1/4 7.28 100-200 best 340ix

I hit 610whp and 620wtq on e40 tune. Was a high reading dyno, based on my mods and the timing/boost I'm running I think I'm probably closer to 550, need to get it on a different dyno. No times yet, but so far very happy with the gc.

Hi yokata, can you please share your dyno graphs?
Preferably stock vs GC. I'm very interested to see the difference between the GC and stock turbo

In my case difference is very big ,stock turbo cant keep up the boost in top end drops from 19.5 to 17.4.Gc runs 24-25psi till the very end.

I love how all these options become available when I get rid of my 340i. I was stuck with the Pure Stage 1 haha, but damn nice to finally see the B58 grow. I guess now I'm looking forward to some hybrid twins.

Hit a deer and the car was in the body shop. Had to reschedule for Sept 1st. Done with all my pre-dyno revisions though and it is fast. Will update with firm numbers as soon as i have them.

Looks brand new though now...before and after

Thanks for the feedback!
Sorry about the deer but nice to see that it's all been nicely repaired!

Still waiting on results for the GC+ and stock motor on pump, E-blends.

How much boost and how many revisions did it take?
