Hi I have a sandrail that had a TT 4.6l engine in it till it spun a bearing. I am in the process of having the 5.0 mmr1000s motor built with twin turbos I should have it by this Thursday. My question is on who to tune it. I have used PSR in the past but trying to get a call back is the obstacle. Any other tuners out there besides PSR. Not to say I wont use them but I am surely taking and suggestions. Thanks in advance
