Just thought you all might be interested. I am in no way affiliated with Diablosport, but just got back from dyno a few hours ago. I will post my latest dyno sheet on my web site as soon as I scan it (No time now, moving). Anyways, with all mods in sig. except headers and diablo tune, I was at 323rwhp and 331rwtq. Then after headers, I went up to 336rwhp and 348rwtq. After diablo tune (and richening my fuel to 12.8) I got 339rwhp and 351rwtq. Just thought you guys might be interested in seeing this. Also, the way the gears shift, it feels a lot SOTP quicker. Next comes my supercharger next year then WOOHOOO!!!!!!!! I'm getting there. Later.

 

Thanks for posting results.

 

3hp and 3 ft-lbs?

A 3HP and 3ft lbs of torque change is statistically insignificant. In other words if you dyno you car tomorrow it could be 5hp down or up depending on temperature humidity and barometric pressure. Good custom tuning should give you more like 15 -20 RWHP, not 3 RWHP. Just my 2¢

 

well, let's see, in general 10hp is good for .1, so 3 hp and 3 tq without actually CUSTOM tuning isn't too bad. My speedo is now fixed for my gears, I changed my fan settings. Oh, and also, my dyno was a SAE run. Meaning it was corrected for air, etc. And yes, you will see 15 to 20 rwhp on a car with aftermarket heads/cam/etc. How can you gain 15 rwhp with a car that already has its air/fuel where it should be? Im not an expert, so I'll probably learn something, but what can you change in the computer to gain 15rwhp? I'll do it tomorrow. Thanks.

 

I just dynoed my car with predator too. I went from 323 rwhp to 330 rwhp with the diablo tune. The car does shift better, not too mention it got rid of torque management. Man, I am surprised your headers added so much power, I'm wondering if that should be my next mod now!
