good stuff!

set your fuel pressure per the tsrm. only time you should be changing it is to roughly adjust wot af ratios's. keep the fuel pressue in the middle of the range spec'd by the tsrm if you can. something i ran into: the rc's hit a limit at 22psi with vac on. Lean idle, and lean low load...

timing being pulled such as knock retard. egts will spike higher when ignition timing is retarded. if you've ever run past 5700rpm where timing is said to be pulled heavily by the stock ecu, you should see egts start climbing pretty quick. (mine went from 1250 degrees to 1400 in a heart beat)

we dont need to guess for you. flip it over and pull the pan. should take you less then half an hour:3d_frown:

gorgeous!

im betting that 10:1 af ratio is actually lower then that with that much fuel. sounds like there is some pirate air getting in. is the o2 sensor calibrated? any exhaust leaks?

how is the bov routed? if its vented, the safc will not allow you to tune this issue out

jdub posted a hard and fast flush for instances like this.. search for it please

you asking for fitment issues? I run 19's on eibachs.

Dr. J mbc here and no spikes or other issues. for less then $30, its hard to beat!

those 4 plugs go to oil, not coolant. only coolant plug i know of is on the side of the block or freeze plugs.

you can also add additional coverage for work done on the car. mine comes out to $15 for an extra $2000 worth of coverage.

my TB has a single port on the back. im pretty sure its a usdm TB (talking about the port for the pcv system). this the port you speak of shaeff?

solution? what pressure plate? You have a clutch start switch override? cold start knock is my guess. let the car sit for a few days and see if it does it again on start up.

increased boost = .028 and a step colder plug.

so far so good. My "squish" fund needs to be re built...
