Recently ive added a yank 3600 stall to my car. When i line up at the track to launch it, it seems to flash but takes off like its in 2nd gear then after a second or 2 it down shifts back into 1st takes off like a bat out of hell. Is it a tranny issue or tunning issue? This is off the bottle.

 

No one has exprienced this?

 

u are probably expirencing "Stall wall" its a component in ur computer that sends ur car into Limp mode... if u havent gotten the car tuned for this to be eliminated then it could happen... get a dyno tune or a mail order tune...

 

hmmm...never heard of that..ill get the car tuned.

 

i agree, i think i tune is a must to get the most out of a stall....and to keep stuff like this from happening

 

yes you definatly need a tune for a converter. Or you can hold it in 1st for as long as you wnat then shift it into second when you want to. be careful as that can cause heat issues if you over rev your motor.

 

Be sure and have the test for PO757 removed ,
