at what point would you say those sticks are overkill. I'm attempting to make a little more power, and have looked at the injectors as an option. What are the downfalls to going bigger?

 

More heat, more smoke, less mileage maybe...

 

As stated above.
But heat is the big killer, especially when towing. Towing with big sticks can be a little tuff but hey you have a 6 speed so you can keep your rpm's up.The 3.5s will be fine, just stay away from the 5's .

 

Your numbers in your sig seem real low. I would try to get ahold of the Smarty Beta with some presure or stack a pressure box with the Smarty. The Flux 2's like a little pressure.

 

I thought this was a joke thread.. A Jeff Foxworthy kinda thing..

Ya know your injectors are to big if_________________

 

...are to big if:

1. Smoke NEVER clears up at Max boost
2. Rail pressure drops to low
3. They are EH's.... (just had too...sorry)

 

Green. I'm running the new beta hot version, this tune does add some pressure but not alot. Do you add a pressure box even though the Smarty is?

Ya I plan to spin the rollers again real soon...........the concencus seems Mustang dyno's generate a lower number then say a dynojet. Rail pressure was not my issue, I was holding 20-22k,In any case I'm lined out to get flux 3.5's.
Results with the new beta and bigger sticks will be interesting..
