Hi!
so I bought a 2008Gt500 last summer that came with a X3 tuner. The car has a 5.8 trinity supercharger, JLT intake, kooks longtube headers, catted x- pipe and stock axelback. The previous owner told me its Brenspeed tuned.
The car runs great, very strong but I felt it needed more cooling, So Im currently waiting for a VMP dual H/E and 170 thermostat to arrive.
I guess I need a new tune when I install this? I also bought 15” rear dragwheels that Im going to use alot so I guess I also need a tune for that so the speedo is OK?
The reason I ask ( I have sent Brenspeed a Mail but have not got a reply yet ) is a new tune is like 250$ and seems like alot for small changes? Maby Im wrong here?
Also, I run this supercharger on stock fuelsystem, stock injectors. The only thing that was changed when the former owner put on the new supercharger was colder sparkplugs and tune, this should be no problem he was told, but Im a little bit nervous eaven if the car runs great. I eaven seen this supercharger being sold in a kit with only sparkplugs and tune.
Should I be worried?
