the td04 turbo in my 04 forester xt 4eat went out not long ago, so I replaced it, went with sti catless uppipe, invidia catless downpipe, 05 sti catback, p&l braided avcs line kit, and flashed stage 2 map on the accessport. Turns out the used td04 I put back on the car is also bad, bearings whine, and blows some blue smoke, yet the car feels quite a bit quicker at stage 2 (the torque is impressive ). I was considering just going stage 3, vf39 instead of staying with td04s, but looking the accessport maps, the stage 2 and stage 3 are estimated at the same hp, with the vf apparently having just a tad more torque (I thought the td04 was the torque monster). I already have an 09 sti tmic, so to go stage 3 all I need is a vf39 and the sti/wrx BPV and recirc hose. Is the vf39 worth switching to with the 2.5l and 4eat? How will 0-60, 1/4th be affected? I'm gonna estimate my car at 0-60 in around 5.5 or 6 at stage 2. Thanks a bunch!
And yes I hope to get it protuned eventually, but for now I'm gonna be stuck with OTS maps. Thanks again
