Got the system installed finally..Had about 400 mile commute to test it out. A bit of trial and error but I am very happy with the system. Mounted the tank and pump under the sled deck. As hard to find room under the hood for the pump..
Anyhow long story short, I have travelled the same commute for 4 years now and there was an increase in mileage for sure. Never had time to caculate what it was I will in the future. On level 5 with the PPE there was a increase in HP for sure, felt like an extra 50 or so with the injection on and off . The big thing I wanted was cooler EGT temps, I didn't notice that much difference. But i started out with a 50/50 distilled water and meth.With that tuning I really dont need more fuel but even so it kept temps the same or below so it is doing its job.With a stock truck I'm told 100-70 HP no prob with this kit..so it looks like I'll cut back on the mix of meth and this should drop EGTs , maybe 25/75 or drop the tune down. when I get the chance I'm gonna hit level 6 which is about 300 flywheel HP on the LMM and run straight water and see what gives. For my app its looking like summer run more water and big tune. Winter drop Hp and crank up the meth, almost have to in this climate Over all very happy just have to get the right mix and set up. Very easy to use screen also. Any experts please chime in with advise

I went with labonte. works well and was an easy install. Also running a 50/50 mix I mixed myself it gave me a 71rwhp gain... on dunbars dyno 7-25-09. Egt's went down pretty close to what they said it would also. So I'm hooked till I can afford one of those bigger spinny things or maybe a compound set haha.

Looks like I need some bigger Nozzles on the WFO pulls. with the HP setting at 600 FWHP it goes thro water like crazy just cruisin ,only running the 2 main nozzles to come on in the top end. So as of now I'm running 100% on wide open pulls with the m7 an m10 and am seeing some reduced egts for sure. Ordered the m14 should be a big help. Im just guessing but what it looks like is with this high of tune, the hp setting could be set lower and run the big nozzles when you need the cooling at WFO..
