That car is super charged though. 13.4 is my goal on pump gas, I am shooting for lower with a race gas track only custom tune.
I have everything except the hood in my basement now.

3 tenths sounds right. That's exactly what I gained with my converter. 60' times dropped from 2.1's to 1.8's, 330' times dropped from 5.7's to 5.4's, 1/8 mile times dropped from 8.7's to 8.4's, etc.

I questioned the stall speed as I know from experience that every time you add more power to a car, the stall speed gets pushed higher as the extra power makes the converter "looser" from the extra torque. My converter was rated to stall at 3400-3600 rpm's, but after a tune it went to 3800-4000 rpm's, and now with a JLT II CAI and tune it stalls in the 4200-4400 rpm range. Peak torque on a 4.6L V8 is at 4500 rpm's, so I'm right on target. Peak torque on a 4.0L V6 is 3500 rpm's, so you will be fine even if your stall speed gets pushed up several hundred more rpm's with more mods.
