Hi, I have a L33 + 4L80e on a 1998 C1500 truck. I want to have more displacement and I'm thinking on goin 4.065 bore (sleeved) to achieve around 6.2L.
The package will include 821 heads, truck style complete rec port intake manifold and a 212/218 .600 lift 112 lsa cam from TSP (I have the lower lift version of it now).
I'm aware of the map/maf/spark tuning on it but, will my stock pcm be able to control it on the right way? In addition to the new injector data and engine displacement, is there anything else to be considered?
Thanks.
