t56 to 4l80e power loss
Just did the Jakes Performance 80e upgrade with a yank py3400 install. With the M6 car made 450hp 491tq. 4l80e it made 442hp 461tq for all you wanting to know the power loss. Thanks

hopefully going to the track tomorrow or saturday and i will update. Best with the m6 is 7.58@93mph with a 1.81 60ft. I was surprised too at how much it didn't lose. It was done on a mustang dyno.

I took my 4l80 to the track last night for the first time since the swap from 6 speed. So far I'm not happy. Drives great on the street but 1.78 60 and losing .6 in et? You would think with a 4400 verter it would leave better. I guess I have more work to do.

Left at 6400 on the stick. Foot braked it to 2500 on the 2 step once. Footbraked it to 2000 the last 2. I'm going to try leaving off idle next week. Also it seems to be pulling a bunch Oh timing at the launch for some reason. MPH was down to 108

why are you using a two step on an A4 and your not turbo?? No need in it, also if its pulling timing on the launch A4s are known for that because it can be so violent on the launch, its false knock. You just need to desensitize the knock sensors and it will go away. Mine did the same thing, desensitize them till it stops. good to go. Also every converters different, but Ive always had the best 60ft just off idle preloading the suspension and letting it rip

a bigger stall that hits hard. Even my Vig 3800 would see up to 6 degrees of false knock on the launch via EfiLive. It would start to zero out in 2nd and by 3rd it was gone, so I desensitized them until it was completely nothing on the launch all the way down the track.
