[QUOTE="TyCorr, post: 1407966, member: 1451"] Trucks dont run the same on the dyno so it means shti to me. Ive had this truck since Oct of 2000 so Im pretty familiar with it at this point. Since you continue to find fault with what im saying Ill break it down for you. My "performance" tune which was a step under the hot tune made like 390 some horsepower. It was the single tune i tried before the all out number I referenced. It was hot and obviously 390 hp isnt a great step down from "all she's got" on an injector that is told to go near 500hp. My "stock" tune as dynoed on several trucks produces 360-390 with 250/200s. So even at that anateur power output the 200% nozzle shines. My egts dont hit 90 Million degrees with 5ms of pw from just a spirited 0-70mph sprint. The way it drives and EVERYTHING else comes into play. Im done with this conversation but for anyone reading this if you want decent power and dont care for sky-high heat, dont piss around with small nozzled injectors. The smallest injector you should buy is a 238/80. Find someone that can tune and ignore crazy advice. Edit:im testing out/breaking in gently my new built trans and as such Ive been driving on my "stock" tune for a week and a half. A guy with a stock truck who wanted a stock like truck would be enamored of the way this setup works. Its ridiculous how smooth and clean it is at ~400hp. And Im getting the best mileage this truck has EVER gotten. Hand calc'd at 19 mpg tank after tank. Thats a sign that efficiency isnt compromised when a 200% nozzle is used for <400 rwhp. The only thing wrong with the first set was they were too small. Call Swamps and tell them their injectors weren't built right. Just make sure to record it because i know what they're going to tell you. And the injectors were sent in and had 100% nozzles put on. I lost interest in them shortly after. [/QUOTE]
