I think maybe you made TOO much power and broke the dyno.


Oh yeah, i just visited their site. It s hows a 03 350z dynoing 408 with a greddy kit at only 6.5psi . That seams to high in hp for only 6.5psi which is stock boost. at 9-10psi i can see it happenint.

 

I have the Stillen HFC and Exhaust and I feel a nice power difference....get a reflash too! Our cars don't do all that great with bolt-ons without a reflash...that's just the way it is now with these newer cars..

 

Stock bottom end and top end? Depending on the turbo size and if they're running cams on the car I could see 400whp.

 

I dont know, it just says greddy turbo kit on the video so im guessing a stock greddy turbo kit which they do 6psi stock. I had oen on my 350.

 

get a ems and tune that bad boy!!! Get rid of the intakes !!!

 

290hp seems really high for stock... imo

Maybe the dealer put the intake on and threw the rest of the new parts in the dumpster. Better look under the car to see if they put everything on. Just kidding ... but it wouldn't surprise me. The dealer told me one time that I needed a brake job and the pads were less than half worn. And they weren't crystalized either b/c I took them apart and looked at them myself.

 

im going to be there next tuesday (technosquare) maybe ill stop by on the 14th

 

Reset the ECU, it won't void the warranty, consider it like rebooting your computer... Follow these instructions:

Let us know how it feels after. Also, since you have an auto, consider the grounding kit, many members here reported big shifting improvements. It might be a nice addition to your package.

 

man this thread just gave me a lot of doubt now cause i just oredered stillen headers and hfc but the only differnce is i will be having a cobb ap could this happen to me ( i mean a powers loss that is) please need advice

 

Wow, how you even found this ancient post in the first place is a mystery in itself.

^^ lol

561G37 I currently have Stillen's HFC and not too long after install I got CEL. So when it does come on for you, call customer service or send a email and let them know. They will give you o2 sensor extension to trick the ECU. Good Luck

fvcking noobs **** me off...ok....290whp...stock...bullshiet...its like 2+2=4 and your saying its 5, no your wrong, that dyno sheet is incorrect, 290whp is impossible for a stock g37, when dynoed LEGITELY. Not bashing toward you buddy, more likely you're dyno-er.

 

ya they might have gotten 290 through some crazy correction factors but thats about it.

 

I hit 292 with intake and exhaust. People hit 260s on dynamics, some even lower! Use your common sense knowledge on this.
