ctx46 Posted October 13, 2002 Report Posted October 13, 2002 here is how... havew a buddie of yours drive 55 next to you, and look down at your gauges, find the differance, and just remember it, the kits to do it arnt to cheep and seldom work properly, if you really want to correct it, go here but they didnt work for my GTP..... http://www.autotransinc.com/Recal.htm Quote
GnatGoSplat Posted October 13, 2002 Report Posted October 13, 2002 I personally think it's not worth bothering for 2%, but I have a friend that bought a Dakota Digital SGI-5 and he claims it does what you want. Your GTP uses 4000 pulses per mile, BTW. Quote
