Dyno pics of NX kit, a little problem See if you can see whats wrong with this dyno <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
First the NA run
<img src="http://webpages.charter.net/imperator/jeff/nadyno.jpg" alt="" />
Now on the hoze (100 Shot)
<img src="http://webpages.charter.net/imperator/jeff/n2odyno.jpg" alt="" />
A little backround info. This car did 353hp/364lbs on this dyno with the mods in the sig (no nitrous, 3.42's). The only thing that was added was the factory MAF and the 4.10's. The MAF I had on the car at the time of the dyno was a factory MAF from a 99 Hawk. The only explanation anyone has come up with is that the factory maf is causing the car to run rich as all hell. . I just put MY maf back in and it feels better already, we'll see if it does better.

Re: Dyno pics of NX kit, a little problem MAF is one problem you had.I'm guessing you had good bottle pressure-at least 900psi.
I had the same prob. with stock MA,fixed with MAFT.
Also the spike on juice dictates you'll need a bigger fuel pump.

Re: Dyno pics of NX kit, a little problem Is it a wet or dry kit? If its wet check your fuel noid, mine was leaking and caused a lose of power N/A. Fuel pressure ? Too Much or the wrong jet installed?
Good Luck

Re: Dyno pics of NX kit, a little problem I cant see me needing a fuel pump if I am running THAT rich. It was only a 100 shot. Bottle pressure was at 1100. Something else I think had a part in this is that the stock maf was from a 99 Hawk, I believe 01-02's have truck maf's. They should be the same, but....? Get this, before when I swapped maf's from my ported one to this stock one, I swapped them and reset the PCM started the car and flames came out of all 4 tips for about 45 seconds (this is through a hooker muffler). That gives me a good indication of how rich the car was running. Also the car has been backfiring and feeling a little sluggish. I just put the ported maf on and it feels a lot better. If this doesnt fix the problem I may look into a fried 02 sensor.
