DC power also makes a direct fit alternator for most applications. I have their 180 amp version on my c6. Mechman seems to have a reputation for random failures in my research so I bought this one....

They're ahp heads ported and milled .030. If you know the bsfc of the engine (I'm using .45 which is where ls7s usually sit) you can use a website's injector calculator to get a general idea of how...

It's full bolt ons heads/cam. No dyno numbers, but injector duty cycle and dragy times agree it's making around 670 horsepower at the crank. I think you'll notice a lot more oil in the can with...

Just wanted to report back here with data for the op. I just drained the catch can on my ls7 after ~2500 miles. I got .5 ounces out of it. This was definitely spirited driving with lots of trips to...

For an extra data point, my ls7 had a silver blade tb. Build date was 10/07. I'm almost positive all ls3s had gold blades though

Should make a noticeable difference. I never get more than a few ounces out of mine even after driving it hard with alot of engine braking

To the op: I have 3 ls vehicles. All were bone stock when bought with varying mileage. 13k to 130k. I've had all 3 manifolds off at some point. I poured a not small amount of oil out of all 3. Put...

Run the tank low and fill it with 93. Every tank of straight 93 I run through my car and truck the content is always very close to 10% where I'm at (Indiana) and the sensors in both vehicles agree...

The bucking is from reversion because of the cam. You won't be able to tune it all out with 17 degrees of overlap. The only thing that will get rid of it is a smaller cam

You need a fuel pump. My z06 never drops below 58 psi unless it's at wot. Even then it only drops to 55-56 psi after 6k rpm. Only other issue it could be is a known problem of the connections in the...

I know it's normal I guess I should've clarified my point that it doesn't matter if you change the value to 55 psi because there's a range that the vehicle will go through when driving

To throw another curveball into the scenario, I run a fuel pressure gauge in my car full time (c6 corvette). It is almost never 58 psi. Cold start it is 61-62 psi. Hot soaked it gets down to about...

Can't go wrong with factory valve covers. They have the best baffling. Aftermarket is always half assed

It traps a few ounces every thousand miles or so. Never measured exactly. I use a spray paint can cap to drain it and it usually fills it about 1/3rd

Go to the mightymouse website and check it out. His catch catch cans are not a gimmick. Most, if not all, of the factory pcv systems allow oil to get sucked into the intake. Fine for a stock vehicle...

That sounds like a cat test being run

I made the changes above to the o2 readiness table and the car likes it! Doesn't go lean anymore and reported tracks commanded eq perfectly. Thanks hjtrbo for the input! Much appreciated

I'll try it report back. Thanks!

Ok I forgot about that one. They are both disabled

I'm catless so cat test is definitely off. Not sure about other o2 tests?

It's not zeroed out. I've tuned that table as well. Or at least I think I have. If I command open loop my actual lambda matches what's being commanded exactly all the way through Injector tip temp...

The latest version 4.8 I believe don't have my laptop in front of me to confirm

Want to see if this is normal or if any of you guys have seen this. I've got an 08 z06 fully built h/C/I. Cam is a btr stage 3. The car runs and drives very well as I've tuned it myself. Maf curve...

I see that on the new 103 tb nw is recommending leaving the scalar values stock. Why would it then be necessary to change the values for the 102? Reason I'm asking is I currently have a 102 on my...

For whatever reason the p59 has some quirks to it that make it act differently than the p01. I have the hot soak tables mentioned. I never could get them to change the fueling. No matter what I did...
