I am getting Allen at Futral Motorsports to LS1 Edit my truck and put some cutouts after each header. He said he can program the truck to not see the O2's in the rear but it is better to put simulators on because the computer is constantly looking for the O2 sensors.

Then I talked to one of my buddies, and he said his friend took off his o2 sims when he got LS1 Edit!! So maybe it benefited him?

Anyway do I need to buy O2 sims or not when I get the LS1 Edit????????????????? Pros????? Cons????? Do I only worry about my SES light staying off??? Or is there a performance difference if I get the true O2 sims instead of tricking the computer into not seeing them???

PLEASE EXPLAIN!!!!

 

Dont buy O2 simms. The rear O2s don't make any difference to the way the vehicle runs. Just trun them off w/ edit and forget about it. Simms would be a waste of money.
