Ok i have weird one for you guys out there.I have a stock rear out of a 98'ws6 and 17s also a t-56 out of a 93' z28.So my question is if a stock ws6 has 3.42 gears and the 93' T-56 has a differnt ratio on all the gears but 6th.Also my speedo is off about 10mph (20 on tach=30) Is there a way i can have Ion from madz28 fix it in my ecm.this is in my 95'

Thanks
