Not to hijack a thread but I'm looking at these nozzles also. I can easily hit 1200F with my RV275's and not sure if I could keep things cool with the 3's. What kind of temps are you guys seeing with these nozzles??

I barely see 1100* with my III's and EZ on the highest jumper setting.

Running empty I have no probs w/ egt's, maybe 1000. Will find out about towing next week.

I'm very interested in what you observe, as I am about to make an upgrade in the injector department. How long have you had this combo and are you happy so far?

i have the rv275 with stage 5 jammer nozzles and i get the best responce on my twin turbo's with it on 3x3 then as i shift into 3rd gear i pump it to 4x4 and then 4th gear i bump to 5x5 and ive pulled my best 1/4 mile runs. With them set at 5x5 the bottom end responce is sluggish then when i get up and going its perfect... so i use 3x3 for good bottom responce then 5x5 for the extrea juice for the long stretch... also when i tow i normally put the box on 1x1 for fuel milage and the fuel is enough to get up and going but not sacraficing economy....

Jaxn51 , I have the RV275 injectors and the Van Aaken V5. I
pull a 7000# TT over the sierras at 7200 ft. with no EGT issues.

Hey guys,
I'm ready to order the Jammer 4's (complete injector) but was wondering how smoky are these injectors? Say compaired to my RV 275's? I can run my egt's up to 1200 @ 31lbs of boost. Do these run cooler then RV275 like the F1 Mach 4's do?
Thanks guys,

Been running these for about a month. MPG is up alittle(if I can drive like a human being). I need to repeat what I said earlier....I am happy but my clutch is not. I am waiting for my tranny friend to get back in town this week to do the swap. I want to put the VA5 back on real bad. I can't believe how these injectors woke up the truck. Going through the gears is effortless.
These things are great, however I would not recomend doing injectors unless you are prepared to do tranny work(depending on how big you go) and of course gauges are a must.

Well, I talked to Jason @ City Diesel and he suggested that I go with the Jammer 3's.(stock turbo)
I guess will see how they work out.
