Ok first of all I have an auto fd.With the following power mods.
Blitz Intakes,Blitz catback,Downpipe,and greddy profec b spec2.
On to the problems im having.The car is fast when its cold.Once it warms up throttle reponse becomes worse and the car has absolutely no oompf off the line.
I checked the stall speed by break torqueing the car and the highest it would go is somewhere around 1800 rpms.No higher.Before I used to be able to get as high as 2500 rpms which I still think is low considering the fsm says the stall speed is somewhere between 3000-3300 rpms.

Im thinking either the primary turbo is going out(because the primary boost doesnt hit nearly as hard as it used to nor does it kick in when its supposed to at 3000 rpms more like 4000 rpms) or this is a boost leak somewhere.Also had smoke coming from the turbo area.

the tranny is shot or slowly dyeing.

The engine has low compression once its warmed up and builds up power slowly untill in the higher rpms.

The throttle position sensor is screwing with my low end power(the sensor is bad in the sense that I could not calibrate it as per the instructions.which leads me to believe that its bad.)

Im open to suggestions.Just so you guys know.The entire solenoid rack was replaced with all new solenoids.The tcs solenoid is also new.All new vacuum lines.
New intercooler couplers.New blitz injectors.New trailing coils.

Other symptoms also include miny backfiring and also backfring when letting of the gas.Unstable idle.Will hunt between 1000 and 1500 rpms.

Thanx guys for all the support through all of my trials and tribulations.I hope to keep on receiving your support.
Nick.

I don't mind small breasts at all. No more than a handful is quite enough for me.
I've never been able to torque brake my auto over 2000 rpm and I've had miserable off the line performance ever since I bought the car. The auto shifts great and pulls hard in the upper rpm range but the initial 2000 rpm blow. I know something is wrong with my car but am unable to solve the problem. Sorry I can't give any useful advice. Let us know if you run into a solution.

speeddemon7

I will.Im thinking its a boost leak at this point.Mainly because I used to be able to brake torque to 2500 rpms and I could literally feel and hear the boost building up to the point where the brakes couldnt hold the car anymore.I even managed to chirp the tires.But now I get none of that.
Its either that or my tranny is pretty much slowly dyeing.Most likely one of the solenoids or maybe the torque converter.I just posted everything I knew in hopes that someone with a lot more experience could maybe make heads or tales of all the info.Hopefully someone does figure something out.

could just be the low compression you mentioned earlier. i doubt the torque converter is shot. is it making any noises? why not take it to a tranny shop and have them drain the ATF and refill it with a synthetic ATF. Then they can look at the ATF and see if it is discolored, or if it has a funny smell, or if it has debris in it. brake toquing will kill the tranny quicker than anything. the FSM says that if you brake torque the car for longer than 5 sec serious tranny/engine damage can result. you cannot get an accurate stall by brake torquing the car anyway.

speeddemon7

well considering that ive done it on occasion I suppose ive been tearing up the tranny little by little.And the low compression thing was just a guess as I havent gotten t he car compression tested just yet.

speeddemon7

ok so ive thought about everything and im convinced right now that I either have a boost leak or exhaust leak or that my primary turbo is fried.I doubt the primary is though because it would probably smoke like hell and most likely would not produce much boost.
Well I turned down the set gain and gain functions on the profec b spec 2 down to 26 and 26 which is where I used to be able to build up 10 to 11 psi without a hitch.Well I sure as hell am not getting the same results anymore.The car boosts but much slower than it used to and now barely produces somewhere around 7.5 psi.Something is definatly wrong here.Im just not quite sure where to start looking just yet.
Another theory thus far is that my stock cat may be clogging up.As I havent been running the airpump becuase it went out about 6 months ago.And with no precat im sure the poor main cat has been getting its *** kicked.

weaklink

ahhh, i remember when i was in your shoes. i didn't know what was going on. power was down. boost was erratic. i bought a hiflow cat. didn't help, then had the motor rebuilt and went single. guess what? fixed like a ****. okay, that may be a bit extreme, but it was better than being up to my armpits in vac hoses, blowing through check valves and pumping a mighty vac.

speeddemon7,

You should start with a compression check. No sense tearing everything apart if the compression is low. Get that checked first. If it checks out ok, then start tearing stuff down.
