new car's #'s
Hey.
Well a few months ago i bought a 2004 evo 8. I love it. I looked it over and notcied some mods and wanted to know what was goign on. I took the car in for a MBC and threw it on the dyno to set it and to see the numbers. this is what came out.
the mods that i can tell are the injen intake and uper intercooler pipe. full 3" turbo back exhaust with No cat. MBC at 20 psi.
It is very rich at 10.5, If i leaned it out would i see significant power gains?
The weird thing about this all is that the car lopes at idle and idles at 1,000 rpm. It sure does sound like it has cams and everyone, inlcuding the shop i brought it to sure thinks it has cams in it. Im confused why its not making more power. Could it just be that the air/fuel ratio is to rich?

No i did not get the car tuned, when i brought it in i thought it would have been tuned by the previous owner if it had cams because i heard the lope at idle. When i saw the numbers I new i needed to get it tuned. Did not have the cash at the time.Do you think the car would run properly cammed with no tune? I want to get GSC s1 cam's in the car. is there any way to tell if its cammed before tuning it?
Its also odd to me that have 295 lb/ft of torque but only 275 awhp.

There AFR suggested that that car has been tuned, although the tune could still use some work.
If this DD dyno's correction factor has never been changed, I would say your #s are about right, especially the Tq #s. A retune may yield another 10whp or so.

Congrats on your car. If you are curious if your car's been tuned do the following:
Go to http://www.tactrix.com/product_info....520f99be159b5e And buy a tactrix cable.
It will allow you to download your maps from the ECU. Ecuflash is the free software to run it , available at http://www.openecu.org/index.php?title=EcuFlash . Start browsing the ecuflash forum here. There's tons of info on tuning,logging etc.

Thank you for the helpful responses!
Im really happy with the car, a great deal better then my 91 mazda millenia . I am going to go and get the GSC s1's before i retune the car from what I gather the car probably does not have cams and has been tuned?
However, it does lope at idle tho and now this is troubling me. I hope the engine is OK. It also idles at 1,000 rpm is this normal for an 8 with a cat-Less exhaust? I will post a sound clip tonight or tomorrow.

hey dubbleugly01, would it not be making more power then 275 awhp if it where to have cams, even a mild setup such as 264 duration and say 10.2 lift something minimal? I'm no where near an expert on cams. any help?
What is the prime AFR?

By the way, GSC S1's are the perfect choice for your setup
