been having trouble with my car on the bottle. alot of popping, surging, etc. that had gotten so bad that it started doing that on motor.
took it to the dyno, found out i needed a fuel pump. got a walbro, and on motor it pulls right through the gears no problem. so i put a 60 shot in leave the timing at 1.0 on the mallory and it doesnt pop or anything.

so i put the 150 jets in (dont have anything in between) back the timing down to 6.0 and hit it from 45 and it popped, surged, etc.
so i figured i needed to take more timing out, so i took it all the way to 15 (that is the most u can do with the mallory) and the car sounded like a machine gun, barely moved forward.

ok so 15 is definetly not a turn in the right direction, lol.
so i put it back to 1.0 (as low as it goes) and do another pull from 45. it pulled HARD. popped, surged 2 times in 2nd gear, then i got out of it once it popped the 1st time in 3rd.

so here is where i am confused, i bought the mallory to retard the timing for bigger shots, but it seems like retarding the timing is making the car run like ****.
seems pointless to even have it in there, well besides the fact i am using it as a window switch as well.
what do u guys think?
where do i go from here?

if it pulls great at the factory setting with a lil hesitation, pulls a lil with it at 6, then does absolutely nothing at 15. it seems i need to go back some more, but this unit is not capable of doing that, unless i am doing something wrong.

sorry for the long post, but i would really like to spray the car to its full potential.
