01 z06 dyno result good/bad?
My car is a 01 z06, went to the dyno Friday and made 429.7/387.3.
Mods are
Thunder Racing RapTR cam(236/242 - .615/.615 - 111 lsa)
Milled TEA 220cc heads
LG Longtubes with O/R X
SLP loudmouth
Dual air intake
The tuner said the stock injectors are maxed out now but this all he could get out of it. I personally wanted 440+ but thats just me.

Reasonable for you to expect 440+, but still a good amount of power. Go get some track numbers and compare. Could be a stingy dyno, never know.
My stock injectors are maxed out, too, but if the car is getting enough fuel to make max power it's irrelevant. Unless the car is running lean and detonating causing a loss of power of course.

Id be disappointed. G5X3 cam only in a LS6 is 430rwhp all day long. Lts & bolt ons only. Stock heads & LS6 intake.

Id be more concerned with the heads over the cam your using. Basically It looks to me that those heads arent much better than the stock LS6 heads.
Im suprised your injectors are maxed out. Mikey from Rapid Motorsports tuned my first H/C setup using stock injectors and I made 430/400 and then I installed better heads, G5X3 cam, & a 90/90 Fast and made 455/413 using the stock injectors. Never had an inssue. The car ran great.

so why haven't you bought new injectors if you're disappointed with the result?
Are those the TFS "as cast" 220 heads? What did TEA do them? Id be more concerned with the heads over the cam your using. Basically It looks to me that those heads arent much better than the stock LS6 heads.

I wouldn't be disappointed. At the end of the day, it's the seat of your pants power that makes you smile from ear to ear. Is it fun? Is the tune smooth?
I went for a ride in my buddies old fox body that was 500rwhp. It sucked. My old GTO @ 365hp could keep up easily. The car just didn't "pull" because the timing was not ideal.
But then again, I bet it's either one of two things:
1) You've got a bottleneck somewhere
2) The cam isn't well-matched with the heads

For what its worth my 01 z06 dynoed 420rwhp with the tsunami cam only, 235/240 .649/.610, and with the addition of the PRC 220 as cast head the car picked up right at 30rwhp to make 450 at the tire. I think the cam size is ok, seems like something might be up with the heads.

Strikes me a little odd that the injectors are maxed out @ that power level, should not be. So what defines max'd out with your dyno operator? If the injector's are the correct ones & you are near 100% duty then the power indicated might be low depending on the dyno type.
If your dyno guy has run a C6 Z06 ask what those numbers report just as a comparison.
When I run on the dyno I data log such things as the MAF g/sec, cannot change the amount of air going thru the MAF, Dynamic Cylinder air & Torque Delivered.These are sanity checks for me when trying to verify & compare dyno's. These are in addition to the normal things such as AFR, Timing, Temps etc.
Anyways the condensed version if your burning fuel your making power, no fuel no power, correct AFR of course.

To the OP your numbers definitely seem low, when I did my cam job I up graded my injectors so that and your heads might be the issues

OP, I would put some injectors in the car and go have it retuned. I've done quite a few setup's similar to yours and the stock injectors max out fairly easily with a decent size cam on a set of stock 243's. Usually baby cam's and ported heads will max injector's pretty quickly. My Formula for instance has the same injectors and fuel pressure and when it was cam and headers only my injectors were running 98% DC. So with that said I would def get some injectors and make sure fueling is good up top. I would almost bet the tuner limited RPM to keep from going lean.

I'd be disappointed too...an LS1 with 241 heads and smaller cam put down just as much power:

Now granted that could be a different dyno and the weather could vary, but still.

If the car made 440 with an ls6 intake you would be hearing "nice numbers "etc.You are basically 10 hp short of that.Don't get caught up in dyno numbers and internet expert opinions .
