Cammed C5 stalling at idle
Hey guys, recently had a small cam installed and the car stalls at idle. Car also has LT headers and vararam. Car has been dyno tuned with street tuning and the installer/tuner is going to work at it some more. Cam is a Comp cam 224/224 @112 LSA with.581 lift. Generally driveability seems good other than the idle problem. Is this a difficult cam to tune? Any suggestions on what need to be corrected in the tune?
Thanks so much,
Tim

Never heard of anyone needing to drill the throttle blade on a C5, tune should take care of it. How much time did the tuner spend on the street with the car? My tuner usually spends between and hour and and hour and a half on the street nailing down driveability issues and the street tune.
However, part of the fix may be raising idle but with an A4 you are then fighting the converter. As hinted to above, you may need a little looser converter to correct this.

Go to a professional tuner with references. Any tuner that cant get your car running properly in one sitting and needs to "work at it some more" is someone to run (not walk) away from.
Thats my 2cents.

This isnt 1973 do not drill holes in your car.
You paid the money to get the performance parts so finish the job and Pay some money do it right and get it tuned by a pro
Doug at ECS had my car tuned with that same cam TSP 224R with XER lobes tuned in roughly 15min. I can put around town with my ac on max and it never once has given me any problems at all

MTI drilled my TB after the H/C install because we were having some stalling issues on my A4 car. It worked to correct the problem but the car DOES want to take off and is harder to stop. Can this problem be corrected with a simple tune now??? How long has this software been available??
This install was done appx 8mos ago. I would have thought that Jason would have been up to par with the latest software available to correct this problem. Especially with the volume of H/C cars that CAME thru that shop. I must say I am disappointed to hear there were other more drivable options available....

MTI did my X1 cam/Stage II head install and runs perfect on my 01 C5. I install Kooks 1 7/8 headers with Corsa indy cat backs. Needed to go with a 3800 stall converter. It lopes low a bit on warm engine start ups but rarely dies. 435 rwhp. Never drill anything on the TB.
