Take her to Chris Wilson, ask him to go over the car with a fine tooth comb and put any wrongs right. He is your closest Supra guru. Do it all properly, first time round in one go. Then get your car down to David P and let him teach you how to service your autobox properly and strengthen it.
I genuinely take my hat off to you for trying, but for the love of all that is holy, make sure your working from a solid base to begin with. With this, your bonnet, your boost controller and engine threads you really need to listen to the advice being given.
The lack of replies when you need help are because you refuse to listen and take advice from very knowledgable members. Mike most recently. The guy was giving up his free time and going beyond helpful but you just refused to listen.
Don’t mind me, just passing through. Not looking for an argument but that needed to be said. Sorry dude. All the best, hope you get this sorted
