I ran Berk HFC's, so I can't comment on TP's.

The only problem is i have no where near by to get a tune.

If you want to get the most and dont ever plan on FI, this is what I would do

Stillen G3 intakes
Fast Intentions Long Tube Headers
Either FI Exhaust or HKS Exhaust
A Grounding kit
Underdrive pullies
Uprev Tune

That will give you the most without building the motor or going FI.

What the heck is a gronding kit and what does it do?

It was voted the worst, most useless modification produced! It's crap. it's a joke. Total waste of money!

Unless your wiring is crap, not much. Just replaces factory ground wires with heavier duty ones.

Really not needed on new cars, and on older cars you'd be lucky to pick up 2 whp.

My first base line pull was 260.4 sae rwhp. Then it hit 264 on the next 2 pulls once we let the engine cool down.

How many miles on motor when you baselined? It will pick up after 5K or so.

I went from 256whp baseline to 305whp with:

Stillen Gen3 Intakes +35%
Stillen HFC + 30%
Stillen Catback +25%
Custom UpRev Osiris Tune + 10%

The +% is what each piece contributed to the total power gain. The Tune after full boltons is essentially to clean up the AFR and squeeze a few more horse out.....

Your baseline is really low -- was that on a dynojet? If so, would you mind sharing the drf's with me if you have them :)

How many miles on engine when you did your baseline?

Seriously, I've looked at dozens of dynojet results now, and anything well below 265 is an outlier (Z eliminator's is close enough).

However, your final results are right in line with expectations, tho'.

ditto, new cars have decent wiring and grounding so it doesn't do much, it basically applies for cars that strip their entire car and get a racing harness so unless you plan something crazy I doubt you'll need it

I can't say that a grounding kit will get much HP, but it did seem to help with drivablity. The 04 350z that I saw at the dealership when I turned wrenches seemed to run smoother ans rev quicker.
