Poor performance
idk if this is on here already, need some help figuring out what and where I’m getting robbed of rwhp. I have an 07 4.0 v6.. upgrades are 4.10 gears, screaming demon coil pack, K&N cold air, 70mm throttle body, spec stage1 clutch, and a Bama tuner(rev-x) . Granted I know without a pro charger or a v8 engine I’m not gonna hit the numbers of the oh holy gts or above. Being said after all the upgrades and so pocket draining I barely notice any difference in hp, I have a friend with the same model but automatic and from the time he hits the pedal you get pulled in the seat not the case with mine. And his isn’t even upgraded at all. So any help at all would be greatly appreciated!! And sorry if this thread has already been started !

I have a V6, InTune1000, 93 Octane performance tune, and I notice a big difference, and
that's without a diiff gear change, and factory TB unit.
I went from 2.86 gears to 3.64 gears in my former '07 Charger, tuned, and was a whopping
difference with those gears, on top of the tune, and it's a 250HP 3.5 V6, 270 tuned.
4.10 gears don't ADD horse power, no gear change does, it just increases torque at the
wheels. Only the ENGINE can produce horsepower. If you don't feel a difference, something
is definitely wrong... With the 4.10 gears alone, you'd feel that even without any HP increase.
I think you feel it at the clutch, and you're being easy on it; you're under compensating letting the
clutch out from 1st. You feel more with a standard, and have more control. It is possible that you
have lightened up on the throttle and clutch so it feels the same as before, because that's what you
were used to.
Other than those things, don't know what to tell you. Only a DYNO test would tell the truth.

Thanks
I do think I’m having clutch problems believe it might be slipping, some rom spikes with out the pull. I do want to do a swap to a 5.0 or 5.4 but can’t find what I will need as far as the wiring etc. if anyone knows where I can find this I’d appreciate it.
