I just took my car out for a spin and I shifted into third and felt near no power me thinking I was just in to high of a gear at the time I downshifted into second and as I tried to accelerate the car acted exactly as if it had a 2 step installed and started "backfiring" I then let off the gas and waited a second and it returned to its normal state My current mods are jb4,downpipes,charge pipe, muffler delete and I was in map 2....is this misfire or something else?

Sorry bruh... OT is probably the last place you'd want to ask for any sound mechanical advice.

I read all that in under 9 seconds flat.

How about basic car information? Miles? (edit) Who Tuned and at what parameters? Last Tune up? Service light?


For fucks sake.

Tune is stated above jb4 G5, 2011 n55 engine and I have about 61k on the car bought the car maybe a month ago so don't really no much on latest tune up

Edit: no engine lights at all

If it's bogging, start with checking plugs and coils.


Standard on 135i with no mods is 45k miles, you might be past due and they're struggling. With mods they should be changed in sooner intervals, 30k is safe.

Was your original post all one sentence?

Sounds like a money shift.
