She lives, and with some very nice oil pressure!

You didn't change computers (I think), so why all the re-tuning? Is the L26 short block that much different?

Same PCM. however, the L26 short block is 9.5:1 compression, the L67 is 8.5:1 compression. So I dialed the boost back a good 3psi, then pulled 5* over all. By my math that should be close. But being a whole different set up I need to take the tune slow.

I'm starting to think someone doesn't want me to finish this before the meet. Because I was in the ER this morning I won't be working on the car. So I'll have to wait until Thursday when I have off work again.

That'* right. I always get my Series III L-numbers confused. But hey, more power to you -- literally.

Can't wait to take her out. Not going to be any time soon though.

since you know what you're talking about, i have a question for you
let me get something straight, the higher the compression the more power right? no?
now L36 and L26 both came with 9.5:1. L67 and L32 both came with 8.5:1 ?

if i am correct above, then why */C engine have lower compression ratio than N/A engines?
lets say if GM kept the same ratio on the */C engines, that means more HP? but possibly pistons might pop?

Your numbers are correct, but I have no idea why they did it that way. Only thing I can think of is making a safe engine for the average driver.

damn..i wish i could make it next weekend, but with mothers day, my moms birthday and my lack of funds it just aint gonna happen

looks good! i wanna see it smoke em again..last time it did pretty good..i betcha it does better this go round

quite possible.

so you're using the L26 for more power?

Well, ya. More power.

You're right, Sam. If I remember correctly, the supercharged engine uses shorter but stronger pistons and connecting rods than the NA engine does. Since the 3800 seems to blow pistons before head gaskets, GM probably decided that the SC engine needed a little more protection.

Although, what would my UIM and I know about boost?
