Thats a 72hp loss. Does that seem right?

No it went up 4 rwhp on a cool moter VS a hot engine.

FWIW.

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.....

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

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'.

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.
