im not trying to argue. but i agree with you. and as i stated before. its like saying to everyone. that every mod they do to their vehicle requires a custom tune to get the benifit of that mod. and yes changing something for the better is a mod as stated in my signature. lol sorry i just dont by it. and for everyone who says im a newbie and etc. and you been working on dodge's or vehicles for years.. thats nice and im not saying anything bad about it.

 

I think the conclusion folks should draw from this is: To get the MOST BENEFIT from a mod, tuning for it is the best plan. Sure, you can see gains from even the simplest of mods, without changing the tune, however, if you clue in the PCM as to what you have done, to take advantage of it, you will see MORE of a gain.

 

so I back flushed the whole cooling system and heater core, and I think I still have a bubble somewhere.

I even parked the front tires on top of cinder blocks to force the bubble out, are there any other ideas?

 

just rev your engine with the cap off and front up, and expect the entire thing to take as much as an hour to do so..
