Default Procharged f150 1/4 time

Well me and freind took his truck out and my car. His truck went 14.0@99mph which i thought was weird cause it pulls so hard. checked the datalogger and a/f was at 11:1 so i leaned it up a hair and it went 13.96@100.1 mph. I didnt understand how it wasnt trapping higher. He said it was hitting the limiter and sure enough i drove it and it was hitting the 105mph limiter a good 20-30 feet before the finish line. So it hits 105 then cuts the fuel hence it only goes threw the traps at a slower 99-100mph rang. It also means its runs faster then 13.9

All the truck has is E-fans,short tube headers,true dual out the side exhaust, and a ATI base kit pushing 8-9psi with 3 core intercooler no tune or other mods.

We allready have a 90mm L maf for it and 42# injectors and 255lph fuel pump comming. Once those are here its getting tuned with the 12psi pulley and we hoping to go deep into the 13's maybe high 12's if it hooks well enough. I figure if its trapping 105ish already before the finsih line with those mods and more boost were looking at traping around 108-110 which is good enough for high 12's in this truck possibly. It would be cool if it did it.

You didnt call me you jew. I would have liked to run my new tranny at the track.

Truck sounds like it needs the limiter removed. What are you using to tune it?

tune lol there is no tune. Its a Fuel managment unit thats how i can adjust the a/f. Once the mods are done VMP will be tuning it.
