Default Unexpected results from 370's

Allright guys, Ive done everything in my signature, and yea, my truck does smoke, but when I was reading about the 370's everyone was saying that they smoked a redicleous amout.. my buddy has some sort of laser cut dv's with stock injectors on a 96 and his smokes more than mine.. I'm young and enjoy the smoke every now and then, any ideas why theres not just a ton of smoke??

The full cut DV's will ad more fuel with stock injectors then the 370's will ad with stock delivery valves.

i dont know why everyone hates marine injectors, ive never had a problem with them,and ive ran them for years without a pyro in both my current truck and my wrecked white truck and never had a problem with them.

sure they may not be the BEST injectors to use, but they are fairly cheap and do there job well.

but to each there own.

Its all in the tuning and placement of the injector with 370's.
They are the most under rated injector for a 12v out there and they are quite frankly the best bang for the dollar when it comes to injectors.As someone already stated,are they the best option for your truck,maybe not as better have came along now,but,will they do the job asked,absolutely.I have seen a modified set of 370's make 792hp on fuel alone at one of our dyno rolls a few years ago.

the problem with 370's has been gone over time and time again they have the wrong spray pattern for the piston bowl, and will spray outside the bowl causing high egt's and smoke, will they make power... yes will they do it efficiently not rely. but they do work

Ive never had a problem with my egt's. I have my probe right in the exhaust manifold and it rarely even gets over 12k. I havnt ever had it hit 15k.
