Hey guys, I'm in Tucson AZ and ran my ExTech twice this week at Hobbytown and CanyonVista.. I haven't gotten a 2013/big boy pipe, can't decide on which so I strapped my 2053 on it just to try it out. Bottom end was decent and the engine really pulled in the mid range then somewhat came to life on the top.. mid-range was the best thought with the 2053 as it is an "mid-range pipe". I'm running 7-10-3 in my diffs (jammin x2 crt) and the truck was hugging the track pretty well. My only concern, I honestly can't get the engine above 160.. not that I am actively trying but is there not a point where you can damage the engine due to the internals not reaching a certain temp? The engine has 1 1/2 gallons on it now and will idle all day.. should I fatten the idle and lean the lsn a few hours? Let me know what you guys think.. thanks! Oh and I am running a P3 plug!
