Hey guys,

How many of us have the 7AT and run HFC's. I had the Berks on my 08 G35 sedan AT and to remove them .. Could not drive the car.

 

Sorry if this is a dumb question but why couldn't you drive the car?

 

Oh sorry, forgot, It heisitated,buck and stumbled all over the place, Everytime I went WOT the car would bog down,trip, fall on it's face then shutter and then finally go.. I had the car at the dealer for 5 months, then they decided to remove the HFC's and the issue was gone..

 

I have test pipes on my 08 auto 5 and i drive my car everyday and i want something louder

 

I know lots of people with HFCs on autos that drive fine.

 

I just dont know, Want to add some sound and some performence,, They worry me

 

I had no problem with Berk HFCs.. That sounds more like a MAF sensor issue that you were explaining if you were sputtering. Did you ever retune after adding the HFCs..

 

its fine mine does it too.... i just learn to drive around it. I have 5AT

It seems to have trouble in D mode getting past 3k rpm for me... it like gets stuck there
If I go WOT in D and my rpms are not 3k or above it hesitates like u described

If i manually shift, it drives perfectly normal.

 

Don't have them on my 7at, but got test pipe on 5at fx35, no problem at all.

 

I don't think that's normal... I'd remove it immediately if my car was doing that..

 

ill be putting mine on in 2 weeks when i get it tuned so ill let you know how mine runs

 

I never had it tuned just reset the ECU after install.

 

At least I was not the only one,, My car would bog in D-DS- or manual, A couple times it almost cause me to get into a accident.( Could not get out of the way)

 

added my HFC today and no problems runs like a champ!! big difference in power putting these`s in

 

Ive had my hfc's in since Jan in my 5AT. No issues and love them.
