On 60# you HAVE TO get rid of your CAT. IMO.
I have GREAT tunes for 60# here in AZ for HPT. You would just need to make minor changes to get your car dialed in. But having that CAT is a NO-NO, it WILL be clogged and you may as well pour cement into your exhaust.
And from my experience (more than most) a 60# injected car even with PERFECT AFRs will last about 10 months, so start saving up $3000-4000.

i have to agree, zex plugs are trash, ive gone through 3 sets. all JUNK........ (gm stage 2 tune) with the zex plugs i find that.... at first they are awesome, but once they get 1-2 months old its time for a new set.... alot of my friends change them at every oil change!!!! (i'm switching to ngks)

Do a couple WOT runs and I will check em out. PM me for e-mail address to send to. It's in your tune 99%.
I had the same issue, most likely pulling timing up top due to changing climates (knock) and the fact that no tune was built overnight. You should have walked him hard with what you have.
The stock SS/SC tune although a pita was built and designed for year round driving so he would not be affected by things as you would be modded.
P.S Get ZEX plugs. NGK's are the weak

the Zex plugs are quite awesome BUT your spark dwell must be adjusted for them to be happy on the bottom end of the rpm range.
i'd bet the NGK's are an issue as well, i've seen nothing but horrid things from the 2step + colder iridium's.
i think you remeber what we talked about....
I run them, and run the **** outta then at times with NO ill-effects.
06blackg85ss, Psykostevo and my numbers can vouch for my tunes as well.
when used properly they are the BEST.
i was able to squeeze another 1-2deg of timeing outta them up top and even more thro the mid range when compared to my old NGK's
now thats ****** funny rite there.

It's called research first my friend. I KNOW what the answer may be BUT you just never know either. If he is not overboosting then how can you THINK you know.

The answer does not always lay in front of you nor does the obvious seem like the logical choice when there is other variables.

*shrug* im sure they perform nice.
but ive seen multiple instances of those pretty little gimmicky prongs they use, dissapear.
wonder where they go?
if you know the answer, you know why i wont touch them.

what can I say... some of these cars are factory freaks... a buddy of mine with a bone stock IRL put down 5 more WHP on the dyno than I did... and I'm I/H/E & Staged.

i think so to but in this case i have always been able to pull on him even when i was stock.Ive been thinking damn i wish i had more power for a bit now just figured i was getting use to the car and it just didnt feel like as much but running him i wasike damn ive lost power

there is a point of running too cold of a plug.
you are .06 off on your mas air calibrations with a 2.79
please do more research the next time you let someone fiddle with the laptop in your car.
as steve said, get rid of the cat. ceramic cores can only sustain a max temp of 1400 degree's. if you really need a cat, find a steel core.

a partly(say20+%) or fully clogged cat will cause mild to extreme over boosting BUT a cat thats on its way out or just at the start of its death cycle will do just that, restrict exhaust gas thus backing up the whole intake system, thus lowering cylinder air mass BUT not raising MAP pressure by 1-2psi(our stock gauge has an error % almost that big). were talking FRACTIONS of a gram with cylinder air mass SOOOOOOO
a slight reduction in that wont cause a big jump in MAP pressure yet those fractions of a gram mean ohhhh sooo much .
its call research first my friend.
i attest that to wicked high cylinder temps and knock.
i've had tons of first hand experiencewith many local cars that i've tuned for the zex plugs with no issue.
but like i said before, if you don't like them then don't use'm its all about being happy with your equipment.

I don't think about this mike, i know these things.

I never asked the question, we all know he is running super rich just by hearing he has to wipe his bumper of the black sut every day but he also has a hi flow cat too soo... I don't think it would be the cat but it doesnt' hurt to delete it. I totally agree with you there. The extra 500-700 RPM means all the difference for his top end.but I also didn't get to see a full 2nd or 3rd gear pull, he stopped pulling after like 6500 RPM in 2nd so it didn't reach it's full cyl air mass either. pure speculation. That's why I wanted to see further runs before and after.

a high flow VS none is a medium size differance so the air mass shouldent be TOOOO far off....
if it is in fact that rich then i would say its not the cat causing the main issue its the fuel. theres so much of it that it'll drop air mas. thats in part why a lean car makes more power.
