Default FLP header dyno results

First, I had heads/cam/stock manifolds with MTI tuning. That is the blue line.

Then, I installed FLP headers, put 500 miles on the combo to give it time to adjust, and dyno'd. That is the red line. It had some knock retard due to too much timing in the program.

So, while sitting on the dyno, I dyno tuned it with LS1edit and my laptop, and that is the green line.

All dyno's were done through the stock Z06 mufflers.

I think these are good numbers. But for some reason, once you got headers, I thought you would have gotten more. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> You did gain a substantial amout of tourque from 3.5k to 5k tho. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I personally think those are very good numbers. 26 rwhp more is alot harder to do than people think. What I also liked was the fact that it pickup up alot more through the midrange especially from 3200 RPM's on up. JMX could you please tell me what your final A/F Ratio was after tuning. Also what tables are you using to tune, I basically use the PE table and the high octane spark advance table. Thanks for the info and hope to see the FLP Install on your website soon.

Biggest gains were mid-range gains. His area under the curve from 4000-6000 looks like it picked up an AVERAGE of 30rwhp. Big gain.

minivette, dont worry, I was hoping for the same thing. The only heads/cam ls1 I know of that's dyno'd more than this at our dyno is an MTI LS6 combo that did 424rwhp through borla stingers, so I guess I shouldn't be too worried.

Anyways, the final A/F ratio is here (its the RED line on the graph), and the final timing table was set to 27 at peak torque, then faded up to 28.5 by redline.

those are SOLID GAINS

cant see headers giving much more than that for the most part, especially in the heart of the powerband. i think u would be fooling yourself if u think he could of got more....JMO

I thought that his stock manifolds were really, really holding him back. I thought that once he went to headers he would have hit 410-415hp+ and closer to 400tq. before tuning.
