I picked up 9 mph but I am still tweeking.....well not lately...only boating.
The Raylar pkg was everything Ray said it would be....lots of torque and power, and sounds awesome as hell.

I have ran the crap out of my Raylar 525 and it has never missed a beat.

The piston issue if there is one scares me though.....

Make sure you always run good gas and there is no reason for worry.

And to be clear, one month old ethanol gas can be questionable.

How can a BCK-103 kit increase reliability when using stock pistons? Now upgrading to the forged piston kit may be another story. I just think if this was pointed out in the first place things may have turned out differently. My 2 cents.

BTW, I think Ray really did what he could once things went to chit and I am really sorry to hear about the family medical issues.
Reliability is a broad term. In relation to the valve train (valves and valve springs) you have to admit Raylars stuff is far more robust. In relation to the pistons, Raylars heads have a radically different combustion chamber design which may relate to less failures. But, in my situation, once you have piston rattle, its all over.... its only a matter of time after i heard the rattle till they implode. cast is cast...

Raylar furnished an ECM with a raised rev-limiter, knowing full well they can let loose at 5300+ ??

I would have thought the same thing blue thunder. I have seen a high performance engine go bad because of bad fuel. Piston # 6 is the first to go. Not once but twice. Give me a 525 anyday of the wekk. They will run for ever with the right maintenance.

And that is why GM went back to the 502?
