    smoke on decel?

    I was thinking it might be the exhaust side of turbo, cause i only see puffs of smoke when i come to a complete stop. what is the smell difference this does have an almost sour smell but can still tell its oil by color. i pulled the o2 sensor and the inside looks like it just has fuel soot in...

    89 supra runs good when cold but like crap when hot.

    I believe the gauge is in the middle of the coolant housing (backside of t-stat) has green connector, with two wires one brown and one solid green iirc

    stock ECU tuning?

    Ok thanks Grim, that does make sense, but now what about at 18psi with the safc zeroed out (no tune) is that just because of the lex and 560s? either way i am satisfied with it, but wanna get more out of it, but not sure on how far i should go with the safc, just to reach its limit. some say no...

    Turbo set up question

    I read that stock 440 injectors are capable of i think 350hp max, maybe a little. Given you are running stock fuel system (pump, fpr, afm, injectors) you will need to run low boost for sure or i believe you will hit fuel cut. +10000 on reading up on how to tune prior to install. Btw what dm...

    Idle / Stalling problems. Advice Please.

    When you unplug the afm iirc you will set the codes for both, but will only see a change off idle? and no codes will not come back unless it is a consistent fault (hard fault). if you have no afm codes prior to unplugging then chances are that is not the problem. Have you pulled and checked cam...

    removing harmonic damper nut?

    i invested in this crazy ass tool that has a pivot on the bottom with a 1/2 adapter, the top has a grip and an area to pound with a hammer, works good for tight spots when engine removal is not a possibility and air tools wont fit. Not a suggestion in anyway can cause damage and possible...

    Idle / Stalling problems. Advice Please.

    May also have a fuel system issue. maybe on a full tank when pump is submerged it for some reason cant supply enough fuel, and when low it can pull the fuel faster? maybe the baffling in the tank? but first things first you found the crack after the afm that needs fixed first. Also maybe its...
