Base tune? I'm building a 1999 GEN III 5.3 to put into my S-10. Using the 862 heads, with a stock lower end & truck intake/coils. Cold air filter.
Cam is a 2000 LS1 unit from a Vette.
Converter is a 1999 LS1 unit from a Z/28 into the stock 4L60E trans.
Also using the EGR from the Z/28.
Exhaust is the 98/99 Z/28 manifolds, modded to go into the stock cat (Y pipe).
Goal is better MPG, with a lot of fun factor. Stock MPG on the Dime is 17-19, stock on the truck is 20 @ 5500 lbs w/3.73 gear.
Truck weight is 3450, gear is 3.42. By my Jethro math, I should net around 25 MPG, give or take.
So, I would assume that the computer (0411) should be tuned as if it a Z/28 or Vette with an LS1 (cam lift/duration). Turn off the VATS and add in the VIN. Will run the upper O2 sensors. Do I need the lowers? Having a Plug & Play harness built. No power adders. Goal is 325 HP.
If additional tune is needed later, is there a shop in the Madison WI area?

Do you mean prime it before you fire? If so, you need a pressure pot. I know my O'Rileys has one they rent for free. I have also used a bug sprayer. It takes a bunch more time, and be sure to spin the motor over by hand either way, it helps get the oil flowing easier.
