Default Went to the track kinda pissed with a tech question

OK I woke up early as hell to go to the track this morning. there was a little rain delay but nothing to bad.. I was one of the first cars lined up. They were just running the 1/8th because the top end of the track was still a lil wet.. I actually ended up being the first car down the track just after they sprayed VHT. I launched at 3k and almost killed it lol.. I was running NA just to get used to the traction.
First run
R/T .....067
60'..... 2.067[:'(]
330....5.85
1/8 ...8.9
MPH..78.71

I didnt think that was to bad.. I did one more pass it was about the same..

OK so now the track opened the full 1/4. I am still NA. I get a ok launch first and second felt fine. then comes the problem. I hit third and it just felt kinda funny.. went to fourth and then it did it even worse. It just felt like it didnt have any power.. I ended up running a 14.2[:'(].. Then when driving back to the pit area it was missing the whole time.. it was spiting anda sputering.. If I just reved it, it would rev fine.. then once I would start to drive it, it would do it all over again.. THen when I drove it home it was fine... errrggggg.....

I am thinking spark plugs. They have about a full bottle ran through them.. Anyone else have any suggestions.

Since it revs fine & only mis-fires under load, I'd say your plugs are fouled.

What are your mods for that 1/8th mile run. I ran almost the same thing today and just wanted to compare

check your fuel system. also do you have cats on ur exhaust. one more thing, if it feels like it is jumping under heavy throttle it may be a coil pack. do a little more investigation and post again.

No man I dont. I am going to change the fuel filter and the plugs and run it again in a couple of weeks. Ohh no cats but what would that have to do with anything.

Hey quick shot.. That was with intake, exhaust,and gears. with a little help from mr. BGF.. but keep in mind my drs are on 18s[&:]

cuz u may have an exhaust restriction in the cats, but since u don't have any nevermind. put an air/fuel gauge on it and see if it is weird.
