Your stock gears are 3.27, so going to either of those is not a problem.


Two issues:

1) You will have to change your speedo gear or your speedometer will be off.

2) If you don't have a chip/tune, your max speed will drop. ie, if your speed limiter cut in at 104 with the 3.27, it will cut in at about 98 with 3.55 and 93 with 3.73's.

I started with 3.08's in the rear and swapped out to 3.27's and my max speed went from 104 to 98 since I don't have a tune yet.

Have it done professionally.

+1 I kind of "assumed" he wasn't going to do it himself...

I have my 21 tooth speedo gear for 3.73 gears. Do i still require a tune. If my top speed is going to be around 150km/h im cool with that. my speed limiter kicks in at 160km/h i believe but i hardly take it up to that speed. Can i buy a tuner and change the limiter myself? I think im willing to buy one now because I also did the PI Intake Swap.

Yes, SCT is the preferred solution on this board. They will help you with the tune for your car and yes, it will remove/raise the speed limiter. I haven't done it yet, so I'm sure someone with more experience will help you shortly.
