Hey everyone,
So i just got my 4.6 back from the machine shop and everything is assembled. I am almost ready to put the engine back into the jeep but now I have some questions about tuning it. The stroker recipe is as follows for referance
1998 block
clearwater cylinder heads 0331 head
258 crank and rods (reconditioned)
bored .030
new factory cam
new bearings all around
new oil pump
new timing set
block was decked to allow running of pump gas
Im under the assumption i am going to need to adjust the map on it and tune it. however it is a california emissions jeep with the pre cats and 4 o2 sensors in the exhaust manifold. If there is anyone that can shed some light on the best way to go about this or anyone that may be able to help id really appreciate it. I am just not sure how to do the tune myself without a little guidance.
