Hi,
I just barely passed emission testing here in Houston. The cat converter on my car is a Catco cat I bought from Summit racing last year.
I was wondering if a Carsound (Magnaflow) cat or Random technology converter would be a better choice to help me lower the HC's on my car.
Here are my results
25 MPH
HC Std =152, result 145 Pass
CO% Std=.97 result .46 Pass
Nox Std=1082, result 872 Pass
Dilution Std >6.0, 14.3 Pass
15 MPH
HC Std =157, result 157 Pass
CO% Std=.88 result .47 Pass
Nox Std=1184, result 859 Pass
Dilution Std >6.0, 14.2 Pass
This is on a stock TTA with 868 injectors, a TT emissions chip with fuel pressure at 42 psi. He recommends 38 to 40 psi, but my car ran like crap until I went to 42 psi. My block learn and integrator were excellent in the 124-128 range.
My coil pack/module have maybe 10K miles on them, the wires ohmed good(Magnacores), plugs were put in last year at emissions testing and I put a big 200 miles on my car this year.
Any recommendations for a CAT (2.5") that will help me lower the HC's?
Thanks in advance.
James
