Tune needed with new gears and TC?
Tune needed w/ new gears and TC? I have a 2002 Z28 A4 with Kooks LT & ORY and Magnaflow catback with a lid, getting AFR heads and cam.
Do I need a tune after I get the gears and TC assuming I had a tune after I got the cams/heads/header installation?
Thanks,
Greg

Your speedometer and odometer will be off until corrected either with the SLP module, a hand held tuner (HPP3/Predator/etc.), or tuning software (HPTuners/LS1Edit/etc).
If your car is an A4 the shift points will also be whacked until corrected.
The torque converter doesn't require tuning, but raising the misfire thresholds can help with it slipping in/out of lockup if that's a problem after the install.

personally i would at a minimum get tuned for wot shifting...some cars end up having slight stalling issues after converters as well as minor other issues...personally the only issues i ran into with my 3500 stall was the shifting problems as the shifts apparently came on too quickly for the computer and it would hit the limiter on the 2-3 shift.

It's really not necessary unless you determine that you don't like how your tranny is performing. I had some tuning done on mine before the TC because I didn't like the factory shift points. I positively hated the stock A4/2.73 programming.

I have an 01 Z28 with a Y3000 2.0STR, coupled to 3.73:1 rearend gears, I definetly needed tuning after the install, my TM had to be deleted, and my shift points changed and idle raised.

Good luck
Stock shift points will make it feel a tad to loose. A good scaling of the shift points along with WOT points will make the stall come alive. You might also run into TM issues if you remain untuned. Judging by your mods with the LT's ect it could already use a tune since the ARF in most cases will be off.

You should read the Converter shaking post. I just installed/had installed a 3200 vig and believe the lockup for this converter needs to be changed in the program of the car. It doesn't happen often and when it does you will notice a light shimmy in the tranny. I believe the tcc needs to be tuned in the tranny section of your tuner.
