Welcome Muzz,
Got any pics u can upload?
Just a heads up, the BA has very poor internals.
U wont find many tuners willing to take it past 12psi or 320rwkw.... even then they can be a time bomb.
Is it a BTR 4sp auto? If so, id definitely keep it under 300rwkw to
If its the 5sp manual? Go less, this mite save your wallet from a 10-15k repair bill/build.
