If the number is all that matters to you, then yes!

Something is up with your dyno #'s. Your torque should not be higher than your HP # going by your mods. Plan on at least 5K for a cam swap done correctly by a quality shop. That would be all parts and labor for either a VVT cam or LS3 conversion. Both require the heads to be removed. Your going to need new pushrods, timing chain, valve springs, trunion upgrade, head studs, LSA head gaskets, lifters, and all the odds and ends that come in most LS3 conversion packages. Need to add an extra $500 for a ZL1 pump to be installed as well since you will be beyond the stock pumps limits. Don't know what kind of injectors your running but they need to be up to task to handle at least 650RWHP while being no more than 75% maxed out. If you have a extra 1.5K laying around get the heads ported by a good place like WCCH or LPE. They have to come off anyway so its free labor plus alot of goodies get installed in those heads like the springs, retainers, shims, seals, better valves, ect. My advise would be to not go over 600RWHP on the stock trans and motor. The cam/heads should put you close to that 600RWHP on low boost.

Partial tune ,canned tune , or tuned based on similar previous that builds that would be probably close, but as each build is and can turn out slightly different I would opt for additional dyno tuning for the mods I do
And expect to be charged for any extra services, and how I look at
The big picture..

You need to listen to people like vader. It's the difference between an opinion that is limited by budget, and what you should ACTUALLY do when taking on a project such as this. A new motor costs more than the things he listed, and you have to redo all your mods...

Engines fail at stock levels that's why manufacturers warranty products. The ls3 stock bottom end has proven able to withstand 650 HP.

Feel free to disagree if you desire.

To me I would look at longevity of the stock ls3 bottom end at 650

Just cause it can does not mean I would

I was hoping someday for 500-550 rwhp. If something is up with my dyno numbers (475 rwhp 522 rwtq) is there an issue with the engine? Oh yes, i forgot to mention i also have 22" rims...

Dyno's are meant to be used as tuning tools. The numbers you listed seem to be a bit off of what most of us have seen. Most of the Maggie powered cars that I have seen are fairly close hp/tq wise with the stock cam. If your car is putting out more tq than hp it sounds like there is a restriction keeping the pressure up (higher cylinder pressure = more tq), which could be a bad sign.

You usually see a little higher hp then tq number with the additions of a CAI and LT's. When we had our local meet most of the Maggie L99's were around 10-15 hp higher then tq on a dynojet with the 3.8" pulley. If it were me, I'd check the high flow cats and see if you could have a blockage.

What kind of dyno were you on? What smoothing method was used? Both of these can play with the numbers you are seeing. Did they check your A/F ratio? I would expect a L99 with LT's, CAI and a solid tune to be really close to 500rwhp/490rwtq.

FYI, Installing the Cam will require you to go down 1 pulley size to keep the boost pressure about the same, which is why you may want to upgrade the fuel pump and check the duty cycle on the injectors. Last thing you want to do is run out of fuel @ WOT. The ZL1 fuel pump should be about $600-$650 installed and is great insurance. Mine is going in next week.

My tuner email me back regarding the numbers : "It’s normal with your motor and kind of supercharger. You supercharger makes instant boost, so you get full boost at low rpms, which added lots of torque and the L99 automatic motors do not rev nearly as high as the LS3 motors in the manual Camaros nor does the L99 auto motor make top end horsepower like the LS3."

do u guys think if i upgrade the torque converter would make a difference? Any precautions should i know about?

Stage 1 ..just in my opinion only.. is not worth the money. Power gains aren't that impressive and lope is generally tame.

My cam probably a "stage 2" as far as LS3 cams go because I did a conversion. However, it is about the same size as the VVT3 which is one of the largest cams you can get without doing a conversion. I felt the conversion would be much more friendly for a super/turbocharger..

I did the Vmax ported throttle body, torque converter, transmission cooler, trunnion kit upgrade, LS3 conversion and cam for $4700 (included labor/dyno).

I went from 370ish to 439rwhp with the cam. So it was about 70rwhp with the larger stage 2.
"Stages" are just packages from different shops. A stage number doesn''t mean diddly. SPECS are what you need to learn and understand.

Assigning a "stage" number to components in a package tend to push you into buying more than you may really want.
