Default New engine-cam code problem

I have an 05, built a new motor with an LS2 block, LS3 top end using all new Texas Speed internals with a TSP stage 3 cam with a 4x cam gear and a 24 tooth reluctor wheel on the crank ( because of the original engine having that to match computer ) I did not know that this would be a problem until now I have everything finished, car tuned but throws a 0340 code and sometimes a 0341 (have new cam sensor, new cam sensor harness, new crank sensor) Car runs great, just hard to start sometimes, not every time. Anyone know of a way to fix this without changing the cam gear? TIA

2005 came with a 1X cam gear so your 4X won’t work…you are confusing the ECM and that’s why it’s throwing those DTC’s.

Right, that's what I've figured out. So is there any other way to fix this issue besides pulling down the front of the engine and changing the cam gear?

No other way out !!…top pic is a 4X and 1X is on the bottom…on my LS3 which has a 58X crank and a 4X cam the red trace is the cam sensor…2 wide and 2 narrow.
