Before SLP LT and Vig3200 install was running 12.9 at 107mph every time I ran. After installs running 12.5-12.6 at 106-107mph. At the dyno had it tuned but everything was on the mark. I figured I would get a jump in my mph in the 1/4 mile with the headers but I'm running the same speed. Can anyone help me on this matter? I was told a cam (TR220 114) will make a huge diffeence. Is there anything I can do for more power without that cam for just right now? Tell you the true I was expecting higher HP numbers but the torque is nice. Also just to take a shotI leaned out the MAFT to 4% and took 2 runs like that(1st-106.77mph, 2nd-107.24mph) Only insight from someone that been through this would greatly help.

 

you could try some cutouts for a bit more power, and yes I bet the cam would help alot, You do have awesome tq though, I have the same headers and the thunder 224 112 cam and my tq is only 366 and my hp is 372,

 

when you put in the vig 3200, you lost 1 or 2 mph. Mine did the same thing.

ASP pullies might help your et a little. When you get used to the converter and it gets a lil cooler, you will run some low 12's easy.

 

I think I'm pretty used to the Vig3200. I can run my 60 foot 1.71-1.73 all day long. One of the things I'm sure doesn't help is the damn near 100 degree heat. ASP pulley is going in soon. Just want my MPH up higher
