I would talk to 5 star and let them tweak it for you. 93 performance is enough for most not to want nor need more.
4.10 seams to be what you might like, but given the tune isn't near what you want, I would buy a weekend car for speed and just enjoy the truck
I guess I could also try an MPT tune. Maybe 5 star is my problem.

well those are only 32 inches tall. I was thinking you had monster truck tires or something. certainly 373's or 410's would be an improvement, but not enough to justify the cost of doing two axles like your truck would need. getting big power out your set up is going to mean big money like one of the other posters was saying...bigger turbos probably. I guess it depends on what your goals are.

I'll keep searching. Next truck will be another 5.0 and a whipple. That'll get me what I want.

yes I kind of wish I had gone with a whipple, however I don't recall them being talked about much back when I installed the roush tvs 2300. I also bought it used, so i'm sure i'm in it for quite a bit less than what a whipple would have cost me.

Have you data logged your tune yet and sent it to 5 star and gotten a revision back?? If you haven't you're doing yourself a disservice, any tuning company sends out an "off the shelf tune" for the first revision and then through datalogging and revisions it becomes a true custom tune for your truck. This is to insure the tune meshes well with your truck and to safely add power..
You will notice a huge difference after a few revisions.

Eh.... My truck did 11.90 with a 60 ft that isn't bad because of the gears only because it didn't stick the rear end well.

I have 3.15's in mine...

The eco doesn't work well.wirh gears because you don't get more rpm like you do on the coyote. You get 6000 RPMs basically max.

Are non of these stations near you? an E50 tune will make quite a difference.

Thats a very high 13 in the 1/4. You need a better tune.
