Installed 222/226 cam and ls6 intake ls6 did nothing for me I installed a cam headers and ls6 intake I did the ls6 intake after the ls1 cause I was missing parts I did the test the same day on the dyno and the gains was zero gains as per my tuner anyway. I have to say that when changing intakes and injectors you have to retune so maybe its in the tune. For me the upgrade didn';t do much but maybe I have to re look at the tuner or tuning ....
I just wondered where guys would see gains from 1 intake to the next cause dyno testing showed 358.9 rwhp and 358.8 so really exsactly the same rwhp a gain of 50rwhp with cam and header upgrade Kook headers y pipe and 3" exhaust I am very happy with the gains now my problem is traction anywhere from 25mph and down it is just crazy I love the upgrade best one yet :-)

I installed a cam headers and ls6 intake I did the ls6 intake after the ls1 cause I was missing parts I did the test the same day on the dyno and the gains were exactly nothing so all you people that recommend the ls6 upgrade from an LS1 intake in my case it was a waste of money gaskets etc I also went with the 28.8lbs injectors ....

a ls6 intake has a flat bottom.do you have the intake you took off the car ?do a leak down or compression check on this engine.most ls1 with ls6 intakes and the baby EPS cam make 385+hp.

Early on, I did a simple bolt on test on a dyno and showed I went from 298HP to 315 hp from the swap alone.
I also added my own EGR tube to the LS6 intake with a ligenfelter part which makes it look like it was stock and meant to have an EGR.
-Was this comparison done correctly? Was it tuned for the cam then the intakes swapped? Was it tuned after the swap then dynoed? You can't just say it doesn't work with no real scientific method to fall back on to validate the testing. There's plenty of real world evidence indicating the volume difference makes a significant impact at all rpm ranges.

did you get a tune the first time the car was on the dyno? and did you swap the injectors on at the same time along with the intake, after the tune?

Literally hundreds of people have documented their gains from this swap at the track or on the dyno, and I'm one of them. So I'm with everybody here in saying there has to be a problem somewhere.
Did you change the IFR tables to the 28.8 specs? If not, that's a part of your issue.

I agree with the others, there is either a tuning issue and/or internal engine issue holding back power, or you didn't get an LS6 intake.
C5s with LS1 intakes didn't have EGR. So just because the intake is EGR-less doesn't guaranty that it's an LS6.

Sorry guys! I opened up a can of worms here loll Nope My motor is fine 42000miles. Myself and my buddy did the exact same upgrade I went with a Yank 3200 he went with a TCI 3000 and we both got 358 and 359rwhp he stayed with his ls1 intake I went with the LS6 with the same 222/226 cam I'm obviously wrong here but my buddy had 308 rwhp and I had 313 before the build but that was dynoed on different days so....He went with a Flowmaster exhaust 3 inch to dual 3inch I went with a Magnaflow 3 inch in to dual 2.5" out both no cats 3" all the way with y pipe!!
I'm absolutely sure I had an ls1 with a v sha[e type bottom and egr and I installed a flat bottom type intake Also checked the #'s to make sure and yes my tuner did switch to 28.8lbs injectors but I did have a check engine that came on about 30mon after I left the dyno and it was a bad o2 sensor so I replaced it and now your making me think that I should go back and double check my tune.
I.m thinking the TCI stall might be more efficient than the Yank here as well anyway I obviously have to investigate further Thanks for the feedback guys
It should be but good question he did have to re tune after the switch maybe that is it
We did 2 cars at the same time same cam with ls6 intake on 1 and ls1 on the other and 1rwhp difference between the 2 cars same #'s
I took my tuners word on it I was there for the 1st tune in the morning then he switched to the ls6 and 28.8lbs injectors called me said the car was ready and told me he couldn't get any more power out of it but now it sounds like its in the tune I will get it re check Thanks a lot guys good thing you guys are there that way we can check that stuff out
It is an ls6 intake for sure I had the #'s ran to make sure it was and the flat bottom no egr gives it away. We did 2 cars same power 1 with ls6 intake and 1 with ls1 as well. I was hoping for 375rwhp but a 50rwhp gain from a cam and headers is pretty good I think my other buddy has a 224/228 Lunati cam with ls6 heads ported and he does 366rwhp so maybe in our area the #'s are lower or our tuner is not great. My car did dyno at 313.8 with a cat back and a lid as well as with the SS3200 that was with the ls1 intake so I don';t know what to say about the 358rwhp that I have now ,,,,

Highly doubtful it the stall. Yanks are known for their efficiency
And the LS6 should really only see gains from 4500 up. Yes it is better but IMO not a dramatic difference especially on a mildly modded motor...

my intake # My ls6 intake # is 12561184 I was told ls6 but maybe it was a switch for thE same thing loll That would just be my luck :-) Now I will get it checked again to make sure and maybe change my 2 o2 sensors they are stock and they have 42or 43000miles now
It would be nice to have 380rwhp instead of 360rwhp I wonder what else my tuner could of done he is considered a good tuner but I know nothing about tuning ....
