LCI M550i Racechip with K&N Drop-Ins

tacocat135 · 07-26-2021, 08:21 AM

Starting a thread for my dragy times. Installed Racechip and K&N drop in filters. Also did charcoal filter delete and have a resonator delete. This run is with a quarter tank of 92 octane and Racechip on Map 7.

How much boost is that in addition?

AmooManiak · 07-26-2021, 06:30 PM

Nice. Did you have the 7.21 software update yet?

Same question! Is this 3.5 with the 0-60 recall/software fix!?

tacocat135 · 07-26-2021, 09:56 PM

Yup, this is with the DME update. Not sure how much boost but its the racechips most aggressive map. Im sure its not as aggressive as a JB4 map 3 though. It feels like the racechip doesnt help much with the launch but i can definitely feel it pull harder from 60 to 100 mph. Its been very hot during the day and evenings in the pacific northwest. Ill try to get a good quarter mile run when it cools down

In my X50 M50i, I was able to shave off about 0.3 seconds to 60 with the racchip most agressive setting. Went from 4.2 to 3.9. Also my 1/4 went down by 0.3 seconds, so it also helped at the top end.

Jb4 map 1 (+4lbs of boost). 94 octane, BMC filters and an X pipe.

Nice work boosted_8, that’s solid numbers for just 4psi boost. Makes me want to do it.

OP has horrible DA and altitude so that can’t help.

Is this (link below) the correct one that you are running on your 2021 m550?

I thought with the different motor that 2020+ would be different than 2017+.

Boosted_8 · 07-28-2021, 01:55 AM

Only downside is I'm limited to map 1 or 6. The wastegate connectors don't fit the 523hp motor. Burger are aware.

Absolutely Correct. OP had terrible Temp & DA.

Too many people don't realize how important temperature and density altitude is!

some people m550s will never be able to reach others 0 to 60 or quarter mile times due to thier DA.
