Re: Experts please ,,, Got first ever dyno with low numbers with some downward loops I dont know whats going on there but your getting raped for power. Your missing about a good 30rwhp+ with thoes mods. Get to an a-tap and check that out quick. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Re: Experts please ,,, Got first ever dyno with low numbers with some downward loops How are they dynoing the car? In 3rd gear I assume. It almost looks like you left it in OD. Also what rpms are they "nailing" the throttle at WOT?

Re: Experts please ,,, Got first ever dyno with low numbers with some downward loops Honestly,I think your exhaust is resticting you.Shorties,really wont do much,same as the flowmaster,get some LT's and get rid of the flowmaster and you should see a nice gain.Also what was your A/F??That could also be part of your problem.

Re: Experts please ,,, Got first ever dyno with low numbers with some downward loops Well if you ask around you'll find shorty headers are about useless and the flowmaster is about sound so maybe your losing 5rwhp or so compared to a magnaflow.You have a lid so I don't think your too far off for a 98.Look at my mods after tuning: 345rwhp 350tq.When you start getting some serious mods like cam,intake and maybe some LT'S you will see those #'s take a big leap. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Experts please ,,, Got first ever dyno with low numbers with some downward loops You're running WAY rich. That's eating up a lot of power I would imagine. You want to have a 13:1 air/fuel ratio for peak horsepower but they say to tune it to 12.8:1 if you run at the track. I bet if you fix your air/fuel problem you'll see a big gain. Keep us posted though. Invest in a MAF Translator and find someone who has autotap. Best investment you'll ever make. BTW thats one funny looking dyno sheet. Wish ie was clearer <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
