Well I had a great experience with Complete street performance in West Chester PA on monday. Andrew is a great tuner and spent alot of time to get the most out of my Camaro.Can't say enough good about him. My Z28 is putting down good numbers but I feel as though it should be putting down more power. I know I can get a little more by adding LT's over my mids but I was thinking it should be in the 415-430 range. Car put down 402hp and 368ft lbs of torque.Here are the mods and crap video below. What do you guys think? THe car does run strong and drive good.

LS6 intake
TSP 233/239 Cam
LS6 heads
Mid length macs w/ORY
NGK plugs
SLP lid
ASP crank Pulley
SLP dual dual catback

I can't see the video, as I'm at work, but was this on a DynoJet, a Mustang dyno, or something else?

With mids and SLP Dual catback I think its good numbers.
Get TSP 1.7/8 headers and cutout you'll see the magic 430rwhp

Car looks good too.

Thanks man. I do think the headers 1 7/8s headers would give me about 10hp at best and some tq not sure about 30 lol. May do a fast intake

Ditch the midlengths and get some longtubes, and add a cutout before the rear axle...that will make a world of difference for you. With your setup now, the car is still pretty stout...just need to free up some ponies with better flowing exhaust.

Seems on par to me for Few bolt ons and a cam. Opening the exhaust will release some ponies!

Numbers are good.

My old SS made 380 with cam only. This car has LS6 heads

Well ls6 heads are good for around 15-20rwhp so that seems right.

My old SS dynoed on a Mustang dyno not a dynojet

The dynos read different, even same dyno different day (both corrected). I've seen a swing of 20rwhp same dyno different day both SAE.

Sounds alittle like the clutch may be slipping.

Torque seems low. I would start with exhaust healthy setup for sure.

Get a FAST and some LTs or modify the MACs to flow better ( port the primaries and cut off the collector, weld on a 3 inch v band and make a 3 inch y with a good merge)

I don't think the numbers are that off.

For example, I have a friend with a 6.0, LS6 heads with similar cam and through longtubes he's putting just at 430.

You with the smaller displacement and 2.5" mid lengths I can see you putting just over 400.
