Default choosing injectors

i got my truck togather and running, 91f350 with q 92 ctd intercooled, ford zf5 and 3.55 gears, took it to my old college professor and found 3 of the injectors are popping off early. so im gonna upgrade i tow with the truck often but not all the time. normally around 7,000 to 8,000lbs or so nothing to major. i dont want PODs because i hear they really raise egts espessially when towing. i am also going to add a denny T pin, and 366 spring at the same time. i want some decent power but still want a drivable workable truck.
thanks

o i already have gauges just so ya guys no

370's seem pretty popular... they're a nicely "rounded" injector i guess. with the right pump tune they can yield a very nice power increase. i'd actually recommend the M&H M3 fuel pin to keep your egt's in check... it looks like a pretty "fun" pin at the same time.

go into the "request a price" section and post a request asking for the M&H fuel pins; ALWAYSWORKING is the gentle man you will be getting a PM from... you may want to talk to him and tell him your plans that way he can set you up with the correct fuel pin. M2's are perfect for towing M3 you will probably get away with.
