After going through other dyno threads, I'm curious if my power level is on par with others?

228 rwhp, gt2560, 2.5" exhaust, 12psi?

This is bad, I'm wanting more power already...

 

Looks acceptable to me. I am not too familiar about the Xede and it's potential, but 228 whp uncorrected at 12psi is pretty good. I say, needz more exhaustz!!! And more boozzts! Easy way for reliable power would be WI and more timing on top of that.

 

Nah dude, pretty normal numbers. With more supporting mods it will rise, ie bigger exhaust. Good to hear that the afr's weren't that high, my good friend goes to clint and ive heard nothing but good things about him. WI/exhaust and shoot for 260.

 

Just turn up the boost. The 2560 should be good for close to at least 15-16psi and a bit over 250whp on a stock '99 head a 2.5" I would bet. A little headwork and a 3" exhaust no reason 275wp isn't possible. The turbo will be nearing it's efficiency in there but that's why you buy a 12psi wategate spring and just rig an EBC switch when you need it. Is this all on wastegate or are you using a MBC/EBC of some sort?

When I do my '99 build in a year or so, it'll be a GT2860 running a 10psi spring for about and an EBC switch to get me whatever I need for around 280-300whp.

 

You should be able to squeeze out a little bit more power. Send me your map and I will look at it.

I would expect a 0.5 difference in AFR's from the WB to the Exhaust tip. So I would add a little fuel just to be sure. Do you have a gauge on your WB?

Sorry, my laptop was coincidentally getting blue screens while I was hooking it up to the Xede so I incorrectly assumed it was the serial/usb cable. Turned out to be a wlan driver. I'll send you my map sometime this week.

With the hot weather I'm getting some pinging under boost at around 4-5K rpm. Is it as simple as adding a little more fuel in those cells?

 

Jesse, in the meantime, add some fuel in those cells.

 

I cleaned up the map some, it was a little was odd. I also added some timing in. Let me know how it works!
