JB4 + MHD BEF issues. Log attached

JB4 + MHD BEF issues. Log attached
Hi there Charles.

I'm having an issue with my vehicle currently.

I took Osiris Z4 for a drive on Thursday night. That car is strong. Throttle response is instant. And power is instant.

He then drove my 335i.

My car is not running well. Its laggy. The throttle response is terrible in comparison. And the car is gutless to say the least.
At the HM auto Dyno day we had similar power within 3kw of each other. Now... I cant even get the TC light to flash. Wtf.
It feels like my turbos are literally missing. Something is wrong.

I had a boost leak. Afzil fixed that. I had the rear inlet off the rear turbo. Afzil fixed that.
I'm not getting ANY error codes. The car has no misfires. Not stumbles. No half engine lights nothing.
So what could cause the insane lack of power.
I have the new coils. New Plugs. Turbos have some whining/siren noise. But would effect the power output like this surely.

Any thoughts

My current mods are:
Stock DP. Insides gutted out.
JB4
MHD Pump BEF.
Stock Charge Pipe (removed upgraded unit as I thought it may not be sealing at Throttle body)
Stock DV. (Removed Forge DV as I thought they were faulty.)
New Coils
New Plugs
Fresh Vacuum Lines
New Wastegate flappers
Reconned turbos.

I have attached a log.
Map 5.
From 2nd gear to 4th.

Thank you in advance.

FF is maxed.

So you can press that accelerator flat you aint gonna make any power.

I dont offer tuning advise on the forum but you can reach me through Firi or Afzil.

Thanks Charles.
The morning after that log I reset JB4 User Adjustments to default. FF is now on 80. And I set FUD to 98. So Ff for the meantime will not learn. It is hardcoded

Cool. Glad its sorted.

On a stock turbo car you want it to learn especially on the Jb4s variable boost maps such as map 5.

Car is not sorted. I just stated that I reset the settings to default.
Still has next to no power.

I'll set the JB4 to learning function again. Try get some logs.
But the fact is still that I need to have the log looked at.
Can you help? Or is this not what this section in the forum is for.

Maybe PM me?

Oh okay...i thought you had it sorted.

It is not possible for me to troubleshoot a car on open forums nor to assist with tuning on this platform. Giving a tip here or there is fine.

Since Afzil has done some work on your car it would be easier and quicker for him to liaise with me to get the car running right.
