The reason everyone is like that is because it's the only way to tell what is really going on. Dynos can be set to read whatever the operator wants so you can't judge anything by them. I can go have a stock SS make 800 rwhp on a Dyno if I wanted, at the track you can't manipulate trap speed.

True dat. I will way a “as measured” Dynojet dyno is spot on about as accurate as you can get. So if in doubt, as for the actual hp reading CF = zero

To the point of your post, it's important to make sure that everything is fine mechanically before getting the car retuned by anyone else. My modification list isn't far off from yours but my numbers sure are. Check and recheck everything that was touched by that shop. Make sure your headers are sealed up, no spark plug wires are cooked, etc., etc.

My mod list is as follows;

Rotofab Dry
PP ported stock throttle body
PP ported MSD
ATI U/D Pulley
Kooks 2" headers without cats
AWE Touring Cat-back
PP 93 octane tune

I ended up making 485whp and 477wtq, on pump 93 using a Dynocom AWD dyno. I'll be getting E85 in my area not too long from now. Brett and I went through almost 20 revisions of my tune to dial it in; to include doing remote dyno tuning. Sometimes, you just have to put your faith in the right people.

20 revisions? Were there parts changed or same parts just fine tuning?

I'm no expert, but I have spoken to Dynojet, and they said this NOT true on the later model dynos.

Hey Forum,

Here's what I did:

Roto-fab dry CAI - installed by me
Soler Engineering TB - Installed by me

Car ran fine no issues, somewhat better throttle response for a couple weeks

Next, (all installed by local speed shop)
Speed Engineering 1 7/8 long tubes
Speed Engineering 3" catless mid-pipes
Stainless Works NPP 3" in axle back
Flex fuel kit
Tune for E85 and 91

Dyno was 419HP and 448TQ (said it was because E85 was more like E50?? and a HOT day, >100 degrees) :thumbdown:

I was thinking should have been more like 440HP. Car is definitely quicker but is just too loud for my taste. I'm talking "piss off the neighbors" loud. I know I'm 53 but dang I'm not THAT old. I've been driving in Stealth mode and still too loud. I had the same set-up (almost) on my C5 Corvette and it wasn't nearly so loud, it did have catted mid pipes tho. I like a good deep growl but sheesh. I keep setting off others car alarms at work when I start it.

If I go with 3" in/out cats will that tone it down (and make it legal) or should I do something else?

FYI, I have factory NPP and had been driving with fuse 51 out and liked it but a little louder would have been fine with me. This is A LOT louder.

Any advise will be appreciated.

Yes, 1 spark plug boot is touching the header on each side so I have heat shields on the way.

Something is very wrong here Should be 440 RWHP easy on E-50

Heat shields are not the answer move to MSD wires with bendable plug end for maximum clearance.

Let me know If i can be of assistance.

Ted.

Correct but like any computers crap in crap out.

The input sensors Accuracy are key to accurate readings.

Man ohhh man!!!!
We need to exchange #s.
I felt the Same as you, my tune came back identical with a tcm tune as well. My tuner is one of the best around and he says with those mods every 6th gen he does gets those #s BUT beats the crap out of other cars that claim more. His dyno reads low but the car is fast as hell. I have your same mods with kooks LTs catless etc. All the guys that have 6th gens go to him and get your #s and crush a lot of people. I actually broke traction at 55 on the highway when I punched it. Far as the exhaust lmao I was str8 pipe and woke up jesus on my cold starts. I put the stock Npp on pulled the fuse LIKE YOU sounded great!!! wanted louder like you!!! lol and ordered the Atak with Npp. it is what is!!! Same story i understand hahahahaha

Alot of pros will say dont sweat dyno #s
Sweat your time lol

I've gone over the installation work a few times now and don't find anything wrong, in fact just the opposite. They even spot welded the clamps so they would not come loose but don't need to completely cut if I want to do something different.

I have gotten on it a few times (no track yet) and its definitely FASTER! FWIW I also got the tcm tune.

Scheduled to get cats and tune out the cold start BRAAAAAP! I go to work at 5am and sure some of my neighbors will appreciate it. As I noted, I like the low aggressive tone, just looking to lower the volume a bit.

It's really, really hard to find someone who not only knows what they're doing, but cares enough to do it right. Speed shops are full of 20-35 year olds that don't have a clue, but love to beat their chests and act like big dogs. I'm not saying 20-35 year olds can't and won't do a good job, but there are just a lot of young speed shop dipsh**s I wouldn't let touch my car.

Just do your research and find someone who knows what they're doing. At the same time, I do agree dyno numbers are not the end all. I would definitely want to see a tune showing your somewhere around 12.5 through the rpm range if on gas, e85 is a little harder to know what afr you want unless you know the blend ratio. As far as tuning though, max power on a dyno is incredibly simple and easy to get. It's driveability that is what's tough. But on a bolt on m6, just about any tuner should be able to get that right. Big mods and automatics are different.

GM intake, P&P IM and TB, headers, 3inch to npp, and E85

Marine dyno:
Moded- 478/476

On a dynapack:
Stock- 420/440
Moded- 550/560

Something is very wrong. I hope you find out what's going on.

If you are down for a drive a guy in San Diego is a LT1 specialist. He is known as the go to guy in the Corvette community. He did all the work on my brother-in-law Z06.
He pulled another 10hp and 11trq out of my car using less timing than my initial tunner.
