TVS 1900 "pink" Injectors
Does anyone have any info on the injector’s maggy uses with their new TVS 1900 kits for the L76 Vortec Max trucks? I have heard these are not the greatest injector due to the Fuel pressure variations on these trucks.

That’s a good question not so much what but when. At start up I see 60PSI, Cruse I see 45PSI and WOT 55PSI. So how the heck do you set up an IFR table with BS like this? From what I understand the system works much the same as the new ZR1 but with less pressure.
As far as the injectors from maggie I will just say the info is very reliable. It’s not that they are crap. They work great at 45PSI but not so well in the upper pressure ranges. Supposedly for the few cars and trucks that have this variable pressure ranges there is a special injector just for these applications and the Pink/purple injectors are not designed for this.
If you seen my IFR table you would

Do the Vmax have the fuel pump controller setup that varies the pressure? I don't know what vehicles have it and what don't. I think some even have a fuel pressure sender on the rail that sends info to the computer so it can adjust the pulsewidth based on actual fuel pressure vs. map. I know the newer ECMs have the tables but, not sure what vehicles they are active on.
