I have been running Revo TNT(regular not R) basically since it came out. I thought I blew a head gasket.............again! So I unloaded the Revo-TNT(regular not R) and then loaded just Revo and had same popping going on. So I just put ecm back to stock and went out and flogged the crap out of it and couldnt get it to pop. Then I tried just the TST (5/5) and no popping. I dont get it, are other '06's having this problem too? Unless I'm draining the rail, but I dont see how because I have Evil Twin's. IDK!!! What do you guys think is going on? My motor build date is 9/05.
