Welcome to the wonderful world of the 57 trim. Mine creeps all the way up to 16psi and then finally hits a wall. If the waste gate is functioning like it should then you can always try to enlarge the wastegate port so it will flow more exhaust gases. It didn't really help when I did it, but...

You don't have to torque them down just snug (I do know that term has different meanings to each and everyone), let the gasket do the work. Also are they toyota gaskets by chance?

Nice numbers for a dyno dynamics dyno -cheers

supradjza80 - I ported mine some and didn't really see results, so I just tuned for higher boost. It would always hit and hold around 15psi. Reiketsukan - The original map-ecu allowed you to get rid of the afm, go to a map set up, and tune fuel. The map-ecu2 allows you to also adjust ignition...

Just like supradjza80 has said about porting the waste gate, I did that, and was disappointed when I got the turbo back on and it still had the mysterious "boost creep". After that I found out by the person who tuned my car that this is very common in the DSM world. It comes from the turbo...

Bypassing the j-tube is just needed to get rid of restriction when using a adjustable fuel pressure regulator and fuel pump up grade. As far as the upgrade to rum more boost, the lex/550 combo is probably the cheapest, but doesn't have as very clean idle. There is more than one way to go to a...

Welcome to the wonderful world of having a upgraded ct-26 and ddp, that no one seems to really mention. I have tried numerous of things to over come this issue, but still cant get below 16psi. I tried to enlarge the waste gate hole on the turbo and recirculate the downpipe, but nothing has...

It took me a few mounths to get a down pipe last december... I was not very happy with the service especially since they were real quick on calling me to get all the info on my cc and then I ended up having to give numerous phone calls and emails to get it shipped. When I finally did they said...

Bump, updated with a pic and only the boost issue left to fix.

Mario I will be there with the supra as long as it runs, if not I guess I will roll up in the IS. 1.SupraMario (Mario / Mark III / Black) 2.MacDaddy_J_420 (James / Mk3 / White)

http://www.supramania.com/forums/showthread.php?t=46793 There is a thread that explains code 51 more in depth than I want to type. Recently I had some issues with this same code. First thing I would do is check the TPS adjustment and make sure it is set to spec, if it is and you still get code...

http://store.driftmotion.com/static/i-stage2clutchkitforr154.php That is what I have in my car, from my views the kit uses a stock clutch disc (toyota) and pairs it with a little beefier pressure plate. Its no drag strip clutch, but I have pushed on it and it still holds strong. Plus the clutch...

I am running the lex afm/550 combo it ends up being pretty evenly matched roughly 25% more air and fuel. This allows for less tuning which is the way to go unless you have the $$$ to spend on a better tuning system. I am also a believer of buy for you needs at the moment and then upgrade...

Updated, car continues to get better.

Updated.... kotu100 - you get you a different AFM on the car

berniek - Wow, you are using quite a bit more fuel pressure then I am. Right now mine is set a 39-40 with vac off and 29psi with vac on. I have checked for vacuum leaks a while back with a snap-on smoke machine, it worked well finding everyone that I had, and fixed them all. It however was a...

Updated

bountykilla - Yeah I am going to do a smoke test here again soon and see what I have. I called the other day about getting some dyno time because a wot tune is all i need and I will drive the car with the rough idle, but there isn't really much of a point until I figure out this boost issue. I...

Nick M - huh?

First of all I updated the first post so everyone needs to re read what is going on now. I fixed the lean issue with the fuel pump and filter. The idle issue is still there and my boost problem has gotten a little worse. grimreaper - looking at the vf's were very helpful, but at idle they are...
