Default Does this dyno number suck?

I have a M6 2002 Camaro SS with 85,000 miles. I have Kooks long tube headers with y-pipe and hi flo cats, Borlamouth exhaust, K&N Filter, Ported stock throttle body, SLP 85 mm Mass Air Flow Sensor (I heard this was crap), Bellow, Powerbond 25% underdrive pulley, 160 thermostat. I couldn't scan the dyno sheet, but i took a picture of it...hopefully i can attach it. I think that the numbers are low. Let me know what you guys think.

Looks about right. You have a good start on the intake tract, headers to get the air out, but you are missing the most important part in the middle, the camshaft. You can try to get more air in but it will always be limited by the stock camshaft on how much you fill the cylinders. You have both engines of the flow fixed but without a cam swap you are trying to push air into a hole that can't take anymore. Is it tuned at all?

Yes it is tuned. Do you think I should swap the SLP Mass Air Flow Sensor back to the stock?

Thanks for the info!! Would it be better for me to put the stock mass air flow sensor back on and take the SLP off?

looks about right to me also. You don't need a 85mm massair on that motor,the money could of went to a cam.

Haven't been there yet, it will be tough with the tires I currently have, bfg radial ta's, all I do is spin. I may go for the heck of it anyways. I will probably wait until next year to get DR's, not sure yet.

Don't change the MAF back to stock if it was tuned with the SLP - that will change the AFR! If you are going to change it back, you need to have it retuned with the stock one...

Exactly. The SLP only hurts hp when people put them on w/o tuning for it, so they run too rich or too lean and lose power. If your a/f ratio is good, then leave it alone. With that said, going back to the stocker shouldn't lose you any power if you retune for it.

I agree w/ both of these statements. Most guys I know that had similar mods were pushing 345-350rwhp tuned, but they did not have cats. So I think thats about right. Looks good to me!
