First, I have greddy fmic, it has properly beaded pipes, ALL do, without t-bolt clamps my old hose clamps would not hold up on dyno after 18psi. T-bolt have better clamping force. Second I use pyrometer egt f * 100 gauge from autometer, sensor taped on manifold runner off of #1 cylinder. Gauge goes from 0-16. Under heavy load never seen it go past 13. Made 380whp on dyno chasis with my set-up and a/f ratio wot from 4.5 rpm-8.0 is avg. 12.0, almost straight linear line. Car is tuned correctly and runs great on c16. Again I think Greddy fmic is very good, probably even better ones now offered in the aftermarket.
yeah, no.

are your wrists more than an inch in diameter? tighten them more.

1300F peak in runner #1? that has nothing to do with your IC and everything to do with your car not running as well as it should, or it's time to replace your dying, innaccurate EGT probe. If you're using an autometer EGT gauge and have your probe in the manifold, that's a problem right there. How are you going to see spikes over 900C when the gauge tops out at 870C? This is why people use greddy egt gauges when they have the probe in the manifold (and it's pretty useless unless it's in the manifold).

I explained before.  Tuned car on dyno with wideband, how else can you know what a/f ratio is.  Dsm link shows around 9.5 a/f under load because using stock o2.  I have wideband installed in car to give me reference while driving, bunged on o2 housing along with stock o2, bunged on o2 housing.  I have never tuned on street, probably take out 2-5 pedestrians or something, hell I would not have a engine anymore, how can you drive half ass tuned.  Who the hell is Chris C.  Anyone who knows me knows I am always thinking about the car and never satisfied with it.  I am usually a nervous reck tuning on dyno. Always have help.  Don't enjoy it until 3-4 pulls where you are safe.  With the new cylinderhead this spring I was lien first two pulls.  Some of the other reasons I have low egt is because aftermarket oil cooler, fuel cooler, radiator.  I have spent way too much money on my car.  Again a good fmic will have a cause and effect and bring down temp. of engine, dah. Greddy is a good one.
a) O2 housing is not a good location for a WB O2. Should be farther from the turbo.
b ) thinking != knowing
c) oil cooler, radiator, and whatever the hell a fuel cooler is, don't change your EGT, unless they are curing knock, which they shouldn't be, unless you were overheating before you added them.
d) people spend a lot of money to put body kits on their car too. money doesn't make the car run better or your brain more knowledgable.
e) good FMIC will not bring down the temp of the engine. it will bring down the temp of the air going into the engine, which, under optimal conditions, will still be exhausting at the same temp. Do you think colder intake air makes the explosion in the cylinder colder?? If it did, it would be counter-productive, as less heat = less energy = less power.

Jason,


As you can tell most of us here are very spectical people. (we just deal with a lot of people who "think" they are in the "know" but really are clueless)


So with that said come out to Uni or to one of our events. - Bring the car and take someone or a spin. Cause that's the fastest and best way to back up what you say.


Sorry if we come off as Harsh it's just from what you're telling us, your car is the exception to just about everything that we've seen/proved ourselves. As you can hopefully tell this forum is full of some really knowledgable people, some who own Shops, work at shop, or have built/owned/tune there own cars to way above average HP numbers.
