I have a Garret gtx55 91mm with PTE1.15 af v-band house. Did a test today and it´s tuff to spool, approx. 8-9 sec. my question is if its gonna make a big difference to switch the house to T6-1.00 af or should I go with nitroz to spool it? I´m running ptc converter, and they say that they can´t build a looser stater to me. The engine is V6 4.3l. If you have any suggestions about this,?
