I don't agree with Johnnie boy don't buy the TTM from isspro as you have to rewire half the truck to get it to work with your keyless entry. the TTM from SPDiesel is a much better unit!! However we all agree the first thing you need is a good set of guages. IMHO there are none better than the Isspro EV guages, they match our factory units perfectly especially at night. I have pics of them installed in my sig. I researched guages to death before buying and Isspro has far less problems than other makers. The best price and customer service came from www.kensperformancesolutions.com . Ken sells a complete set of all 3 guages with a-pillar and complete installation kit for under $300.00 delivered to your door. Tell Ken that Kevin said hello. He is a great guy to deal with. His installation kit has every wire and connector that you will need right down to the zip ties. Other places want $40.00+ for a kit like this. Ken's step by step instructions are very easy to follow and walk you through the install. If I can install them anybody can. I can email the directions to you, just PM me. After you have the guages in I would go straight to Jody Tipton. he is earning quite a following on this forum for his tunes and when I am ready he will do mine as well. I like to buy from folks that stand behind what they sell regardless of warranty periods, that is why folks like Ken, Greg Evans and Jody are great to deal with. Tell Jody what you are looking for and if he doesn't have something already tuned to meet your needs it will dop a custom tune for you. I hope this helps. If you need any help on the guage install just PM me and I will help you all I can.
