Which map or box?

Hi

I have a m240i, looking at upgrading the performance in the next few months. I have looked the Dinan box but it seems very expensive for small gains, 2k seems a huge amount for a box and from reading the gains arnt massive. I know it’s keeps your warranty.

Next I looked at the jb4, seems to give better gains and is a fraction of the cost at £500. Can you get the jb4 to show gauges on the I drive? I have a idrive 4. Does the ecu show that you had a jb4 installed? Is it easy to remove.

Last option is the guys that tuned my old Megane, RS tuning. He said they can get the car to around 440 bhp and 440 lbs. so much better gains than the other 2 options. They are well know for safe maps. About the same price as the jb4

Really stuck what to do! My car warranty runs out in 1 months and still 50/50 if to get a extended warranty.

You could wait a bit. I'm pretty sure DINAN is working on the flash for the b58 for the stage 2. You won't see the same gains as the JB4 because it's not designed to push the engine to its max. They do their best to keep things with a careful balance of power and reliability.
