N55 Performance Mods?

hogwldfltr · 08-23-2019, 08:42 AM

As some may be aware I recently had the FTP intake and charge pipes installed. Since this area seems to have been the weak point of 35i I'm now considering doing some performance changes. I'm pretty impressed by how much better the car feels now. I'm curious as to what others feel are the best mods for the F25 with the N55 engine? I'm thinking that starting with a chip is the best. If so which is the way to go? If not what do others recommend.

I'd say:
BM3 Tune
VRSF Catless DP
VRSF FIMC

great, reliable combination.

I stopped in at a BMW performance shop near by. The recommendation they made was to only consider BMW upgrades. The reason is the 88K miles on the vehicle. I guess I'll follow his advice and leave the car with the FTP mods only.

I'd say that you shouldn't try to modify your car, if you really think that their advice is best.

Just walk away...

Pretty impressed how it feels after swapping to a ftp charge pipe? There are literally no gains other than insurance your plastic doesn't blow.

Placebo effect perhaps, or maybe it feels better in comparison to the lack of power when the charge pipe grenaded.

There is no gain in HP but throttle response could improve because the stock ones can ballon up under boost.

Placebo helps a lot too lol

Just feels more responsive; not saying greater HP or torque. Less lag feels better. Check out the following, fwiw.

and one more...
