I just bought a 98 Z28 6 speed H/C/I car and it was dyno tuned with 3.42's but the gears are going out and whining like crazy so i have to change them but I would like to put in 4.10's but that will throw the speedometer off. Is there a fairly cheap way to calibrate the speedo?

thats the thing I don't have a tuner so I was wondering if they made anything to just calibrate the speedo that was cheaper than a tuner. If I buy a hypertech will it mess up my current dyno tune because when you plug it in it installs its tune or can I just calibrate for the gear.
