edit: he runs an ls1 https://www.performancetrucks.net/fo...d.php?t=418985


he said he gained nothing, but he also said he only retuned for injector size, i dont know if he re-dyno tuned the new intake on there?

 

Ah ok.. what about the price difference of the LS6 vs Fast 90/90?

 

havent found any good used prices of the fast yet.. ls6 is around 350 shipped on tech.. i think i will hold out for a fast setup.. if stew already wasted that time and money and only gained .2 seconds, i cant see doing that.

drive careful on your roadtrip!

 

after thought, the 4.11's will also make your dyno #'s lower, but after I talked to a few friends we all came to the conclusion that your engine is trying to breath through a straw. one of them went as far as saying to sell the dry shot and get the fast setup.

I think your right about not bothering with the ls6 intake, though for a smaller engine I wouldn't say it isn't worth it. .2 seconds is the equivalent of taking 200lbs off your truck for the quarter. I wouldn't say its not worth it, and it would compliment a good set of heads when the truck intake would hold them back. I think its a good choice for a 4.8-5.7, but not for a forged, cammed 370 with stage 3 heads. go with the 90/90 setup when you have the cash.

next thing that I would make a priority is traction. but i'm pretty sure your aware of that.

that thing is honestly kinda ugly...

 

I'm thinking being tuned for dry nitrous is making you NA performance suffer. I would switch to a wet kit. Run it at the track and let us know how it does.

 

any track numbers on this thing yet?

 

i ran it a few weeks back, couldnt hook up. went an 8.44 on street tires, spinning pretty bad. 60' was around 2.4

soon as the weather clears, me and the boys are going back to the track.

 

With the dry nitrous, your A/F ratio needs to be about 11:1 to 11.5:1 where as a N/A engine needs 12.5:1 to 13:1. Plus you can add more timing on top of that. Your tune is what is getting you the low NA numbers for the most part. There is more left in it. Don't worry about the dyno numbers...go to the track!
