I know its possible, but it would prolly run alot worse since all the new stuff is new to the computer so it wont really know whats going on, it'll just know how it was before....I think ima just run up to summit and get an H pipe here soon. Anyone know of a cheap place ? Summits is 115 i believe.

I drove my trickflow topend kit on a fresh rebuilt motor for a year before I got it tuned. In fact I just got it back from the tuner last night. Didn't harm anything, just need to get new spark plugs is all.

How do you adjust your fuel pressure?
My car is running really rich.

i have to do my timing by ear and feel. its more like a move it alittle one way drive around and work it one way or another
you are going to wreck something timing it like that.
get a timing light, they're only $35-40

you need an adjustable fuel pressure regulator to adjust it

I am on my 2nd year driving with my h/c/i and no tune except lowering the fuel pressure and upping the timing to 16 degrees , the computer will need some time to adjust, drive it for a couple weeks and it will adapt to the increased airflow
