both runs were @ Edinburg International Race Track


when i ran my truck back in feb 2 2007 i ran a

60ft= 1.88
1/8mile=8.39
1/8mph=81.67
E.T.= 13.19
MPH= 103.04
this was with stock stall, 28in slicks (hoosiers), nelson sdtune with 3.1pulley@10lbs of boost and 18*'s of timing,

and i ran my truck today 11/2/2007 and the only difference was tuned by tiburon (file) with street tune (not sdtune) and with the 28's slicks, 3.1pulley@10lbs of boost and 18*'s timing

best run

60ft= 2.15
1/8mile=8.85
1/8mph=83.03
E.T.= 13.70
MPH= 101.22

now last wed 10/31/07 ran the same time with the pi vig 2600stall, so it feels like it's spinning off the line, but it also seems like it bogs out once i hammer it, i tried stalling @1600rpms, off idle, 1300rpms and same results, wondering what could it be, the truck feels strong, cuz i know if i get my 60ft back to 1.88-1.90 i'll be in the 13.1x's-13.2x's, im spraying the meth @5lbs instead of 3lbs and it seems to work better,, anyone have ideas im here to listen,

 

What was wrong with the sd tune?
To me sounds like a maxxed maf. But i don't have much experience with FI.

 

there was nothing wrong i switch cuz my new tuner is about 4miles away, not 200+miles

and how is that about the maxx maf, my a/f ratio is at 11.7-8

 

Whatever it is is the first 60ft...not substantial amount of difference on the mph.

 

Like i said i'm just tossing out ideas as i ahve very limited exp. with FI.

 

would running the granatelli maf be the problem, cuz i ordered the stock one with screen, and what does max maf mean, causes of it

 

i was running the 28's slicks hoosier with only 10lbs of air, but it seems like when im staging i stall about 1000rpms,1400rmp's and 1600rpm's, then when i hammer it ,like it hesitates' for a bit then it wakes up, it's not the tranny,cuz 2days ago i switch stall's back to stock and said that it was excellent condition,

 

it looks to be all in your 60ft. like someone else said your mph is there.

 

It's my understanding that the granatelli maf's are crap. They don't work nearly as well as the stocker according to three differant tuners i've talked to in the past when i had one.

 

wat was your best time with Nelson tune with ur current setup with the Vigilante stall??
