Hey Guys/Gals,

Well I put my first mod on an SLP Loudmouth exhaust and today I have discovered a problem with the way my car shifts. I have the A4 and whenever I use my passing gear now the motor revs really hard and it sounds like it's hitting the rev limiter then it actually goes to 6000 RPMS and shifts. Also when I’m going about 30-40 miles an hour without changing my foot position on the gas it will rev up for a bout 2 seconds then it will go back to normal.

This is freaking me out; when I installed the exhaust I followed all of SLP's directions, used exhaust sealant to secure the parts and checked the O2 sensors for damage.

I have the feeling that this is a computer issue since the exhaust gases are flowing at a higher rate and maybe the computer isn't interpreting the mixture right because of it. Has anyone else had an issue like this? I'll probably take my car to the dealer and see what they say or if they can re-program the computer if needed I’m just concerned here I'd be grateful for some input.

Thanks!

 

LS1 's computer is a learning compiuter so it might just be getting used to the new flow....about 200 miles or so it may clear up. See if anyone agrees.

 

yeah the computer does take some time to get used to the flow. Also the change in tourqe from low to high will affect the way the car shifts.

 

Well,

Apparently the dealer says somthing is loose in my tranny sort of concerning at 17,800 miles..

 

Your catback has NOTHING to do with your tranny... much less any thing in the computer

 

i'd say the auto tranny is shot!

 

Well I'll find out tommrow,

If my tranny is shot i'll be pissed the thing has hardly any miles on it.

 

Yup,

My tranny was burt to hell aparently, I called my service advisior and he said the only thing orginal in my tranny is the casing now. Totally horrible how the tranny could fail this early my car has 17,800 miles on it. The sad thing is the service people called me 30 mins after my inquiry asking if my car had a kill switch because it wasn't starting now ....lets say i'm not exactly pleased with tihs sitution..*sigh*

 

Be ready, trannys are expensive and my dealer 'attempted' to void my warranty becaus i had an aftermarket lid and a flowmaster catback back wh en my car was still under factory warranty... My fuel pump went out...

 

They are covering it under the MFG Warrenty

 

Do you beat the car? This kinda has me concerned because I go to the track every now and then and my car has just over 21K on the clock. Wonder how long mine will last.....if it goes out I'm gettin an M6

 

Your the type of person that likes to rub salt in other poeple's wounds aren't you.
