Hercules trouble.. any ideas?

Ok so my mods are as listed below.. I just got the remote tuner from PHP a few days ago. so here's whats going on, i want to see if i can get any insight as i havent been able to get ahold of php:

low end and normal driving feels about the same, when i get on it a little i notice i build 30psi quick on the gauge (doesn't feel any different). but when i hold the thing to the floor, it makes a whole lot of noise but it wayyy slower than before. i've tried both looney and eric's xtreme, neither have any top end. i know its not the tranny slipping. the low end might be a tad stronger but nothing much. i'm not blaming the hercules so much as i know so many people have had such good luck. any ideas? i'm not going below 50psi fuel pressure ( i know thats getting dangerously close) but any ideas?

edit for clarification: the truck is slower with herc and a tune than with just a tune, not sure if you guys would think i just meant there was no top end gain, which i wasn't expecting to get

Does it feel slower?? Or just that there isn't an increase like you expected?? I ask because it might be that you are at the limit of your fuel injectors for delivering fuel to the motor. Not saying you are but just trying to throw out ideas.

its not feeling slower, i have a tendency to watch my speedo when i'm wot, and i know its slower. theres a stretch coming out of work that i always hit 80 on, and i struggled to 55-60. it doesn't even have the put you in the seat feel that it had before. i'm wondering if its just asking too much? and its cutting something out? no idea

throwing out ideas is exactly what i'm looking for! thanks

i haven't, i see there are others loaded onto the programmer, but i wasn't sure if i could use them. i will try 40 or 80 tomorrow if it lets me

i was really looking for all i could get, because i'm getting studs here in a few weeks and i dont tow at all.... so i'm assuming i can take about as much tuning as i can get

I would say that something is not right somewhere. I have mods in sig and I have the Atlas 80 on my FICM. When my truck has stock tuning it is faster than an agressive tow tune with stock ficm, when I put my Looney Wild or SPD on it it is stupid fast. I have a little bigger than stock sticks, that might have a little to do with it.

Dumb question but did you pull the fuel relay out before tuning the ficm? Hercules should make your throttle touchy

i pulled the ficm relay under the hood, pretty sure i got the right one as there was no buzz when i turned the key

i was expecting it to be more touchy, but its not at all

I'm going to have to try the 40 or 80 and see how it goes.. maybe its just too much for the sticks? idk

I revert it to stock first, drive it a bit, and then reload the FICM tuning.

A couple of things strike me here:
1) You only have 50psi of fuel pressure at WOT, you aren't delivering the kinda fuel that tune was designed for.
2) You are peaking at or above 30psi of boost. Depending on how your tune is written, your VGT cycle may be dropping out on you at the top end (assuming you are on stock turbo, this would be an effort to avoid an overboost condition).

Naturally, you may want to get your tunes re-written for this FICM tune, though I am not sure any of the tuners have gotten to that stage yet.

Did you get the loaner programmer, just to load the one tune?
