Im currently having a bad idle, miss and stall issue also. Once loaded up it goes fine. Jamie from forced performance has advised faulty lifters. Getting done this week. I will let you know if it fixes it.
The old one had a good run but was time for an upgrade. The true trac is great. Drives like standard when you are cruising around and locks when you put the foot down. Alot more control. Im really happy.
I went a GTX35. I was told by my tuner it would come on full boost about 500rpm later than the precision. Refer to my signature. I was happy with the end result.
I have a set of these pbr calipers on my BF2 Xr6t ute. I only purchased front calipers and braided lines from race brakes Sydney. They fit under my bf 17's no worries with the 325x32 rotor.
