Check your alternator volts @ WOT
Were you in third gear and then went wot or did you shift from second to third and it fell on it's face?
from 2nd to 3rd yea
how do i check my alternator volts at wot
Sounds like pprv
If it only happens when you change gears then you have two choices, shift faster or do the pprv delete. I speed shift and have never had the dreaded hesitation between gears. I just have the hesitation on track when i go wot,then full on brakes and try to go wot again.
i got the lethal budget return style fuel system dont that delete the pprv
Yes, that means PPRV is not the problem.
I am having the same issue. So far I have changed the plugs, cop's, fuel filter, and frps. I took the car out for a short ride and noticed that a whine (not in boost). As the car is always on a charger I put the charger on and the following morning the battery still wasn't charged. So did a little searching and found a few others have had this issue too, and the problem was caused by a bad alternator and or battery. So to be on the safe side I ordered a 220amp alternator. Should be here this week. I have a dyno session scheduled for the 28th if all this does not solve the issue. I did notice when I 1st start the car after the battery has been charged the A/F gauge reads between 13 and 14.7 at idle. When I shut it down for a while and restart without charging she reads between 14 and low 15's and jumps around. So I am thinking it might be a charging issue.:shrug::shrug:
maybe that is the problem cause the other day my battery light came on after i started it after sitting for a week but then the light went off after 20 seconds
