lately when i am driving and i got to press on the brake the rpm's like to dip down into the 100 -150 range. clutch in or out. in gear or out. and the car almost dies. 2nite i had to get on the brakes a little harder to avoid a deer and the car completly shut off. WTF!!!!!!!!!!!!!!!!! mods in sig.. please help! I also have a Twin disk clutch

 

did you have your intake when you got tuned?

 

yes. the car was flashed for everything thats on it. except it now has stock exhuast with a test pipe rather than a 3 inch TBE

 

Make sure there is no wires that are getting tangled or pinched by the break peddle. My friend had a problem like that but that was whenever he pushed the clutch in.

 

the rpm's drop even wen its in gear and clutch is out, but u push on the brake? and they drop?

 

Vacuum problems... perhaps?

You brakes are vacuum assisted so if you have some kind of leak there of course its going to stumble.

If you got a boost gauge sit her at idle and use the brakes, check for fluctuations in the vacuum.

 

+1 on this
also check the battery

 

That happens to me alot. I have 280 cams and when i come to a stop in a hurry ,ie.... traffic light, toll booth i have to make sure i give it gas a little to avoid bogging out. My tuner adjusted my idle aliitle above 1000 rpm. It rarely does it now. It's the cams.

 

hmm my idle is already at 1100.. how much vacume should my car read at idle with 272 camshafts. because im only at about 10-11.

 

yes exactly. could it have to do with the intake i have on it?

 

anyone else have this happen?

 

Thats pretty damn low...

My stock cammed evo and stock displacement runs at a cool 21in/hg. I think either your cam timing is out, you have a vacuum leak, or those are just beefy cams o.o;!
