I would take the #8 washer with you , once you find a shop that knows the R4 . Thats the most important part . They need to know it or they will have problems with the settings . No big deal , but it is some thing that needs to be known before you start tuning it

 

Here, I'll make it really simple for you... check out Coastal Dyno & Performance (<--- click on the link). It's about a 2 hour drive but this is where you really need to go to have the Split Second Box Tuned Properly.

Make sure to have the Vortech installed per the instructions, make sure to have the correct washers, stock timing, etc... when you go there. If Orlando Infiniti (OI)changed ANYTHING on your G, have them put it back to the stock setting before going to Coastal. OI does not know the first thing about mods. They didn't even know what the Crawford Plenum was and on one visit the technician changing my oil (while the G was on the lift) asked me if I'd done any other mods to my car. I guess he couldn't see the headers, intake, y-pipe, wheels, springs, etc...

 

Well...your car, even with the wheels, does look like a stock '05
