Sorta... if you have enough to support it (nobody can really say if you do or dont, would have to scan), then you should be able to run a 3.4 on a stock pcm and make as much power as you would on a not stock pcm... most stock PCM stuff I see has good WOT AFR... and not many people run more than stock timing.. so I dont see where you would make power by "tuning" it. You may make it richer to fix knock, but you would be making it slower the more fuel you add.... how much slower i dont know.
What do I have to do too find out if I have any kr?
