<DIV>did some gteching tonight with the big head installed, i just had my main tank and the aux fuel tank filled the day before(430 liters) so i know my weight was over 8000 lbs, but according to the gtech made over 3 runs and averaged out(which were all about the same1/4 times(.002))</DIV>
<DIV> </DIV>
<DIV> as for the total hp figured out by the the speed and compared to my runs with the stock acuator it was about 100 plus lbs of torque added, and 50 extra hp, with the stack i was using, </DIV>
<DIV>total hp for the 3 runs averaging around the 510hp, on friday i will be running on a mustang load cell dyno to compare the numbers, as for the boost it is making around 34psi in 5th gear, and egts seam a bit lower, also turbo seams to spool up quicker, and less smoke, still having bursting problems with the big va stacked, if i find a way i will send the gtech image resultshttp://www.dieselplace.com/forum/smileys/smiley4.gif</DIV>

as you can see the forth run was done with the stock actuator, looks positive for the banks big head, now just hope the turbo stays togetherhttp://www.dieselplace.com/forum/smileys/hihi.gifhttp://pic3.picturetrail.com/VOL22/566829/847939/72504047.jpg Edited by: fredw

looking at it from another graph the major gain came from the 5th gear, probally where the bigger boost was seen over the stock actuatorhttp://pic3.picturetrail.com/VOL22/566829/847939/72505665.jpg
