Hey guys just installed z06 cam and 243 heads on my ws6 with the stock tune idles fine (revs go up and down a bit at idle sometimes) just wondering if I should take it easy until I get I tune? Or is it going to be okay at WOT? Will the maf recalulate the fuel added with the air? Or am I risking engine damage running to lean or rich at WOT

Broke a valve with my stock heads due to crappy 98 push rods so I got a 243 heads already assemabled didn't feel like swapping springs just wanted the car running so I put a cam in that matched the springs, for a shitty cam pulls pretty good higher end I just hope I don't break anything els from stomping on it without a tune

Dyno tune I just been busy at work mybe I'll have time next week to get it done, before the h/c my m6 threw down 306 to the wheels with just long tubes plus I added ls6 manifold while I was doing a swap so I hope to get similair numbers to the ls6's

Your LS1 tune is probably lean at WOT if that's an 02+ cam and 243s, so I'd tune it before getting medieval on that bad boy...

DesertLS1, my T/A and I agree with your calculations...
You can see my bolt-ons and LS1 dyno numbers, and my LS1 was all stock including the intake. I put down 308/324 before tuning.
This is all on a Mustang dyno, so bump my numbers 15-20 to compare them to a generous dyno...
I'm hoping for around 375-380 from the LS6 with all the same bolt-ons.

It can be done. Why is the question. If you save the money for the upgrades save a little more and get it tuned. There are no down sides to getting it tuned. Other than having to pay for it I guess.
