I just got a set of twins. HX40 and HT3B 26. I was thinking of running New Era 330. I dont want to throw all of my money out my exhaust. But are these injectors enough fuel? My truck will fuel to 3k, is it worth it for the 4k gsk?
On the HX40 it has a wastegate, do I set that at 40 psi? I am going to add a couple of blow off valves.

Set the wastegate on the HX40 to open around 20-25PSI, The 4k springs are worth it, and you would be better off with a 370 injector or bigger. I am going to take mine out and sell them VERY soon actually...

The free gsk is not enough rpm for the twins? I did that mod on my dads truck, buut his is a 94. On the injectors the edms are the way to go? Thanks for the help

The free GSK would probably be enough, but if you get the 4GSK the drivabilty will be better and fuel to 4k, or you can remove the medium spring and rev to 3200 and the rack will keep full travel until 3000rpm. On injectors they are all ok, as long as they have the correct spray pattern, some EDM's can be custom made to have a tighter pattern so you can run more timing. I think mine are made to be good until 26* I want to say...
