Default Problem with my motor.

About four months ago I had an LS2 408 put into my car. Since then the car will not hold a tune. What could be wrong? I have a brand new computer in the car, new harness, and vat sensor. Has anyone had this problem before.

I doubt it is your computer if you could give more details of your enitre setup.
A local guy bought a 408 sometime ago and has a hard time tuning it himself especailly spraying . There are many things that are took into consideration from heads to pistons , cam etc...
