brought my ws6 to the dyno last saturday finally...

i just bought the car earlier this summer from texas...since i have owned it i have added

flowtech LTs with ORY
z06 clutch

when i bought it it had
aftermarket lid
flowmaster catback
hypertech power programmer
hypertech 160 therm
and a few other small things


when i brought it to the dyno i got 314 rwhp and 321 tq

also it is a 99 so no ls6 intake...is this decent or should i probably get a tune on it (has no tune now)

- the #'s are definately low, take off the flowmaster and get a tune, you'll be in the 335 - 350 rwhp range

-there are a ton of different cat-backs, and countless posts of opinions of them. The word on this site is GMMG or tru duals are the best you can buy. I have magnaflow and like it, especially for the $$. Some of the others you wont go wrong with are Corsa, Borla, and SLP.

Like the others have said, that is a low dyno. For comparison sake, my bone stock 02 dyno'd 313 hp, 328 tq. Ditch the Flowmaster, maybe mess around with the Hypertech settings (they're not really good for a whole lot, if any, hp though).

For pre headers & ls6 #'s those are good. intake & lt's should be about 330-340rwhp.

Well, all the adds NEVER stack up as advertised. I was EXTREMELY disappointed with the numbers on my first dyno about 2 years ago ... just wanted to go home and fucking cry.

Don't take it too hard. I made a few chnages and had it tuned and was at 360 RWHP/370 RWTQ with only MAC's/ ported TB/ORY. It was mostly in the tune. As everyone has said here, ditch the FLOWBUSTER and get the tune. You'll be glad you did.

Save your money, get a cutout(35 bucks, plus however much to weld it in) get a tune and your done dude. No need to go changing catbacks yet, just save your money man and do the cutout. You can also just run a bullet muffler off the back of your y-pipe as well. Thats also cheap, efficient, and sounds great.

The tune is important. It will help adjust your a/f back to where it needs to be, because when adding headers shit likes to go way rich. So do these 2 simple mods, and you'll be a happy camper! :nod:

Find a reputable shop in your area that has LS1 edit, or HPtuners. Those are the best money can buy(for the stock pcm anyways)

Get a good dyno tune, and I' m sure your car will wake up. In my area, a good tune, depending on combination, will run from about $400-$500. Who we have here, is really good, and I' d recommend him to anyone. Hell-of-a nice guy, and know his ish. A good tuned really woke my car up. I picked up at least 15RWHP with his tune, byt my guess, and track times. The only way you will maximize your combination is with a dyno tune. I hope no one takes this the wrong way, but, IMHO, one can not get a tune, for THEIR car, over the internet. Each car seems to be different.

I wouldn't push the panic button exactly. Remember a dyno is a tuning tool. Without a baseline run, it's hard to tell what your mods have done for your car and you never know if it's a stingy dyno or not. Did you get an air/fuel ratio reading with your dyno run? If it's way off, I'd probably spring for a custom tune but I'd probably put that off if I was going to add a cam or heads later. If it's pretty close, chances are you won't gain a ton with it. Like others have said, the Flowmaster probably isn't the best flowing muffler around but the average gain for headers and catback is around 20-30hp total so I doubt a muffler swap is going to add up to a bunch.

Oh yeah, lowering the car kinda undoes or negates the gain you get with the lcas and the lower mounting point. The arm angle change is somewhat undone when you lower it. Overall, the lower center of gravity generally hurts traction on a relatively slow car like ours. A taller car tips over backwards easier and puts more weight on the back tires. Lowered cars sure do look purdy though. LOL

get a magnaflow or SLP LM..not a hooker...if you cant see through it it aint worth it.
plus they are about the same cost and the magnaflow quality/stainless is way better.

like krexken said, if you lower the car, that's not going to help with wheel hop. look at your dyno graph and look to see is the car missfiring. also you may be suffering from knock retard. other than that, Stock LS1 dyno all over the place, so I wouldn't be too concerned
