The difference in HP between the Machs and Jammers IMO is very small. I have run different sets of both. What differences I can tell was that all the Jammer injectors made my truck idle with a lope.I pulled them out several times and changed out the injector tubes,O-rings,copper gaskets etc,but the loping did not go away.these were complete injectors,not just tips.When I switched to the Machs,my truck ran smooth as silk,idled perfect, with less smoke. The Jammers made good power but,I will pay more for the Machs.

I went with the RV275s only because I wanted NO worries with EGTs. I have only once hit 1000 degrees - the rest of the time it stays around 8-900 degrees while towing. I read before that the Mach 1.6s do hover around 1200 degrees at times.....but, search and see what you like. Mine are fine as is and I am happy with my power levels now.

 

I can hit 1450* with the 275s, empty. I have yet to really roll into it with a trailer behind it, it may shatter the pyro!!

 

yeah, but what number is your edge on?
those 275 arent causing all that heat, that edge is.
when i had 50hp injectors,i barely saw 1150 at WOT and i mean WOT!!!

fueling boxes will always cause that much more heat over just injectors.
