I have an A/F gauge in my car. Here is the dyno sheet

 

Well what does the A/F gauge read? I'm still going to say that you're running lean, because take indy car racing for example. The have 3 different settings during a race, 1) Runs pretty rich and they get the most power, 2) In the middle normally used if they are leading a race, 3) This one runs really lean and is used to save mad amounts of fuel

Now that i wrote that I feel like a smart ass who says things that ppl already know

 

When I am at WOT the A/F Gauge reads all the way to the left like between 10-11. So I am assuming the car is running super rich.

 

One easy way to tell if your running rich is by the smell of your exhaust. not to mention your gas mileage will most likely be ****

 

Well my gas mileage is **** and when I step on it there is quite a bit of black smoke coming out the tail pipe.

 

Definitely sounds rich to me, I just don't get why the header was glowing if it was running rich. Normally its the opposite.

 

If my cat was clogged I thought I read somewhere that it will cause your header to glow. The guy on the dyno was like I never seen this before and told me to take a picture of it ahaha.

 

who did your reflash? did u get it done at the chev dealer or somewhere else? If it was chev i would take it back it back and tell them to do it rite.

 

It was at the chev dealer. But I thought the stage 2 tune was suppose to run really rich? If I take it to the dealer they wont know what to do lol.

 

true u have a point there, are u trying to keep your warranty?

 

Cat's are the dumbest thing ever. I had an 84 monte carlo before this and with both exhaust systems I had neither one of them had a functioning cat. One was gutted and the other exhaust there none installed. Whenever I get a d/p I dont think I would get a cat for that reason, they get clogged and just makes it so the exhaust isn't as loud.

 

I dont really care about the warranty, but when I first had the stage 2 and the intake the car felt a lot faster than it did when I put the header and the pulley on. So I am thinking either a clogged cat or maybe I screwed up one of my injectors or soemthing. Would a messed up injector cause this?

 

i cant see it cause u havnt done nothing to the injectors since your stg 2 rite? Could possibly be a clogged cat, that would be my starting point for sure b4 u go any further.

 

yah I am going to get someone to check my cat next week sometime. I was just thinking maybe I messed one up when I put the 2.9 on or something. Like over worked it.

 

That is the reason I went catless on my balt. Dont have to ever worry about it getting clogged. its just loud as hell now. and j-ro lol glad you like my sig. i really dont care for him. IMO he enforces being a mod when he wants, and other times he doesnt.

 

Where are you located? Maybe it was hot and got heat soaked. Do you have any cooling mods?

 

Yeah just get the cat checked and go from there man. Any exhaust shop can check it -and- replace it if it's messed up.

 

got it checked out and they said there was no flow once the car was ideling for a bit. I guess that means my cat is clogged. I just put it on a month ago to.

 

Well that my friend was restricting some crazy ass hp...shouldn't stage 2 be around 260 whp?

 

should of been 240ish whp..something went wrong

 

so the cat is restricting a lot of horsepower. They said there was no flow through my downpipe.

 

Whos dyno??? Dynamite? or JD Racing? Also the 91 Octane is also to blame, I had knock the whole way through the rpm range with 91 Octane!

 

it was a dynojet at the apple blossom car show. I should have hit a lot more than that. But the cat is clogged or something. How much power would a clogged cat restrict?

 

Evidently a whole **** load!! Especially if your header was glowing red

 

yah the glowing red was really bad. Will get it fixed and dyno it again
