N/A to TII swap: Speedo not on cue.

So I made a TII swap into my NA 88. I have 16" Konig wheels and OEM size tires like the TII and I'm pretty sure my speedo is off. It shows about 130km/h when I'm actually going 120km/h. I have the GXL LSD, is that why? And to fix this, should I get bigger tires? Right now I have 205/55/R16. So should I go 215/55/R16? Or 205/60/R16?

Thank you.

N/A's have 15in. wheels therefore if you did not swap the clusters you wont have a accurate reading.

edit: and as far as I know all north-american clusters go up to 260.
