What's the Next Big Upgrade After DP & Tune?

Hey guys,

'22 M340i. I have a JB4 on map 5. I have been playing a little with higher octane gas and ethanol mixes. I have a catted VRSF down pipe, and an intake.

Dragy Best valid 0-60 in 3.46s and 1/4 in 11.57. How would I get into 2.XX and 10.XX territory?

I see setups with the Pure 800 and e30 get. deep into the 10's. That's an investment I could potentially make. but wanted to check with you guys. What did you guys do after the common bolt-ons?

Pure800 makes the most sense after the mods you already did

Big turbo and custom flash tune. You will need to send your dme to Femto in either Russia or Finland to have it unlocked.

ECU unlock should be your priority followed by either a HPFP or Pure 800/ larger turbo.

No aftermarket HPFP for this platform. Just straight to Port injection.

I didn't see you mention having an aftermarket exhaust setup so I recommend this:

mike@x-ph.com can hook you up.

Next setup would be getting your DME unlocked and getting a real tune. You will see a real difference in power and delivery! JB4 is okkkkk for what it is, it getting a real tune will be a game changer

I’m about 2 days away from getting my car back from my tuner and will be at:

Full Exhaust (catless DP)
Pure 800 Turbo
Port Injection (upgraded charge pipe for fitment)
And BM3 beta Flex Fuel

Excited to see what the numbers will be- Assuming we will be around low to mid 600’s to the wheel for HP. Will do a write up with everything once it is home.
