That's my current setup and no problems so far, been 3 years.

I would also suggest to get a timing light and double check the timing. I fixed a supra yesterday with similar problems by realigning the cps and timing it correctly.

how much boost you'll be running?

Go ahead IndigoMKII, my FC went from 10psi to 14psi. On stock injectors the spark plugs will have a whitish color after a while (i ran this setup for two years) so i'd do it until you find the 550's

Usually people break the 400whp at 17-18 psi on the 57trim, how much you got with the boss jr?

At oP fuel pressureis 38 psi. I'm buying wideband and tuning tool this winter

20 mm/hg at idle and 46 psi fuel pressue. the screw wasn't backed out all the way for the dyno but it makes no difference... however i had fuel cut at 15 psi also with a 62-1 ct-26.

I'm looking foward to break 400whp with my 57-trim, With tuning and DDP and 3-4 more pound pounds if boost, it's a really realistic goal. From little info I could get, on a stock engine, 17-18 psi and supporting mods will break the 400whp mark.

I'm set a 14psi, no fuel cut there but usually running at 10 psi, plenty of power already

Thanks for the advice guys, but I don't run the car too hard, I usually stay at 10 psi. I'm looking to get an FI\C 6 or 8. I'm running an HDI SBI-C eltronic boost cotroller and no boost creep issue.

Here is the video: http://www.youtube.com/watch?v=tTil7pM1lYQ 10 psi==> 333hp/339tq 14 psi==> 371hp/395tq Hitting 399hp/414tq just before hitting fuel cut @ 15psi :3d_frown: Not tuned yet!

I think a vid would help. What makes you say that it' surge? BOV flutter sound? Have you tried another BOV to make sure?

Did you do some work on the car lately and might have dropped some coulant in the pipes? I'm having the same issue, when I check my pipes some colant dropped there while doing a turbo job... Now I have white puffs once in a while but it started exactly like yours. Might be the turbo going...

Needs a paintjob but still looks decent
