You might have used all your HPOP up and it was letting you know.

That's because you do it so often that you burnt out the bulb Steve!

Jim, that just ain't right. Light will never come on with 65 added HP. Takes 140 SMOKE to light up the light.

It is probably a p1211 which I believe is an ICP code. It means as Rick stated, the hpop pressure is not at the minimum that the PCM is calling for.

when you let off the go peddle fast like that on a WOT run the ICP will spike and set the SES...if you pull the codes im sure you will see this
<TABLE style="TABLE-LAYOUT: fixed; WIDTH: 456pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width="80%" align=center border=0 x:str><TBODY><TR style="HEIGHT: 12.75pt" height=17><TD style="HEIGHT: 12.75pt" height=17><TABLE style="TABLE-LAYOUT: fixed; WIDTH: 456pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width="80%" align=center border=0 x:str><TBODY><TR style="HEIGHT: 12.75pt" height=17><TD style="HEIGHT: 12.75pt" height=17>P1211 ICP Not Ctrllable - Pressure Above/Desired
</TD><TD> ICP Not Ctrllable - Pressure Above/Desired</TD></TR></TBODY></TABLE>

</TD><TD></TD></TR></TBODY></TABLE>

the diablo 65hp tune is like running the 20HP dp tune..just not strong enouph to set the light....

If the check engine light is only staying lit for a few minutes then it's normal with a DP. Jody can change the parameters in the PCM so it no longer throws the code. It's just a query that the computer is asking the sensor and the HPOP isn't keeping up with demand at WOT. It probably drops below 2100psi. I think that is where it is set at from the factory. When I got the new tunes at Smokin' Jody had changed the parameter and it no longer throws the CEL. It's a soft code and it won't hurt anything, but I didn't like seeing that light as I am sure you don't either..
