Crazy KR

Hi Guys, I received my aeroforce scangauge and I went for a little drive... I gunned it and saw up 6 KR at arround 5000 RPM... I did TWO runs 0-150 KM/H, I popped the hood and my manifold was glowing red...

I have a ZZP 3'' DP with a Highflow CAT,Air intake, Autolite 606's, 180 tstat, Borla 2.5'' catback, Stock pulley. and im running 91 octane gaz..

Im looking into headers now,

What could be the problem?
 


could it be my cat? I installed the catback yesterday, My front manifold was glowing red last week with my stock exhaust after 2 runs...
 
How many miles on the cat? I doubt that it's toast. Doubt it would take much to cherry stock manifolds. I might try AL605's and scan again.
 


Is your car a GTP or a GT top swap? Sorry if this is a stupid question..your user name suggest that it is a GT.
 
I dont think my cat is clogged because when i swapped my exhaust line i started the car Open DP and i had good pressure coming out...

So all stock GTP will glow red?

and what could cause a lean condition or back pressure? (im french so i migh not express myself properly lol...)
 


Lean condition means there is too much air for proper combustion. So... bad or dirty MAF, vacuum leak, tiny pulley, etc.
Back pressure is caused by exhaust restrictions, of which you really have none.
 
Glowing manifolds result from running 10 degrees of timing as well... so if you are still laying into things at 10 degrees it will get pretty warm.

Engine load goes up because TC is locked. Either need to tune the trans for a downshift, tune for less timing vs MAP, or run higher octane fuel.
