I had built an LS7 by Late Model Engines of Houston for a project car. Link if interested:https://www.thirdgen.org/forums/ltx-...ld-thread.html. I have been out of the racing/hot rodding game for some time. I'm not well versed in the modern computer tuning or what works well with this particular setup. I understand how most systems work but only on a general basis. I'm using the Holley Dominator Computer for my build. I have already gotten the power, trans,and engine harness for this setup as Holley makes them ready to go. What I need advice on is which MAP, IAC, and TPS sensors to use. Since this is a swap build and I'm am replacing all wiring with new harnesses, I don't have a baseline application of parts to choose from. So if you guys could offer some suggestions as to what particular parts to use I would appreciate it. Engine specs:
