243 heads/ws6 store hot cam/fast 92mm intake and TB Did the job in a week.
Installed:
hot cam
pushrods
truion kit
hv oil pump
dual valve springs
fast intake 92mm with TB
and ported 243 heads
fast fuel rails
32lbs injectors
Now I am dealing with p0300 code.
checked:
compression
coils
plugs
wires
vaccum lines
injectors
all 4 exhaust manifold pipes are hot
have not tuned yet.
Any ideas thank you..

00pooterSS explained in another current P300 thread
"Usually with a 300 you have a common source issue. Bad fuel, low pressure, bad MAF or MAP. In other words not usually a single cylinder issue like A plug or A wire."
So I'd probably check the MAF, MAP and fuel pressure.
Hopefully 00pooterSS will see the thread or one of the others that excel at trouble shooting. Tuning would probably help.
Glad to hear the H & C is installed

Thanks for your .02.
Ive been reading it’s a common issue that the tune will
fix that code.
car runs great, idles at 1000
but sometime is a little shaky.
I ran it for about 20 miles and
it was more explosive after the 20 miles.
Hopefully tune helps.

any ideas on good LS tunners in the area.

In this case his single source issue is the cam with overlap that is literally causing a misfire at idle on all cylinders.
Do not chase the P0300 untuned with a cam. The cam is causing it and the tuner should turn the 300 code off.
BTW, I assume that cam is a bit of a lumpy idle cam, if so it's likely 100% of your issue.
To further explain what you mentioned about my explanation on the code.. The P0300 code is "random multiple misfire" so you're looking for something that affects all cylinders. Fuel, cam, timing, MAP, MAF, CKP sensor, CMP sensor, fuel pump.. things of that nature.

Tuner..... only one "N". That's where auto correct got ya.
