I have my car up and running now, and just figured out how to record the scanner. I did a few WOT pulls at 3k and some general driving. Hoping a few of you pro's will look at my tune. Thanks~!My first power log.hpl3_18_16 Vette Tune.hpt

More information please.
What's done to the vehicle, mods etc etc.
What are you curious about?
And you aren't logging enough data, you should be logging knock retard, injector duty cycle, bank 1 and bank 2 injectors pulse width and your fuel trims are not working. Also your o2 sensors are not working either, they pretty much both steady at 100-300mv and at times jumping up to 700+ but they are not switching back and forth like normal.

If you don't post your tune and logs when you have questions you aren't helping yourself.

Corvette filter/regulator. I've tried two. Neither runs close to 58 psi. The first one regulated 68 psi. Replaced it yesterday with another Wix. Damn near 78 psi at the rail. Today, I fired the car and the pump sounded funny, like a whistle sound, then quit. I popped the hood and there is WELL over 100 psi at the rail. I presume I blew out the Corvette filter/regulator. I think I'll run a quality inline high flow filter and a good return type adjustable fuel regulator.
Agreed, definitely get an adjustable regulator. Cool sounding build!
