mike thanks for the advice, as always its taken under advisement.
I've driven several cars on T34, and only one a T38, and i must admit i didnt notice the lag difference between the two.
Escpecially on Andy Engine, aka My engine, and this was when it was only running 12psi due to weather conditions and constantly spinning up.
Im phoning UT soon and going to ask for a price on both a T38 and a GT30.
