help needed...cutting out

[jonahs_supra]

So yesterday I installed my new turbo and fmic
Turbo is a 46trim ct26 with 12 degree exhaust clip
Fmic is a Cx racing with new couplers and clamps
At 1st start up it was idling great with 22in vaccum
Took for a short trip and it began to huck and buck during light acceleration
WOT boost would build to 12psi by 3000rpm but wouldn't feel like its hitting boost til 5000 rpm
When I got home I found my cps wires where cut, twisted and taped together...repaired wires
I checked codes and found 24, 34,41 and 51
41 has been there since I bought car 7 months ago but has never actually made CEL come on

Today I reset codes and went for another short drive
Same thing happened
Rechecked codes and got 34 and 51
CEL came on after hard acceleration
But I was not hitting fuel cut
AFM is almost new with just 5000 miles on it
51 is due to me not having a/c

After I drive the car for about 5 minutes it seemed like the driveability would smooth out better with no bucking
Had same problem about 5 months ago and it came out to be my AFM was bad so I replaced with new
Drove it everyday since with absolutely no problems

Any thoughts?

That's your problem right there.

isnt 34 for fuel cut?
going to do a boost leak test in a few hours

would a boost leak cause my car to buck during light acceleration?

decided to diagnos the code 41 for tps sensor
wire IDL i should have 12-14 per TSRM
well i only have 4.5 at tps connector
checked wire at ecu and the same 4.5v
wiggled wire at ecu connector and nothing

would this mean my ecu is bad?

That was my point. You said you have 34 but weren't hitting fuel cut. Can't have one without the other.

.....would this mean my ecu is bad?

The TSRM is wrong. With the TPS plugged in IDL should be zero volts (or nearly so) with the throttle closed and around 5 volts with it cracked. If IDL doesn't behave this way odds are the TPS is bad or needs adjustment.

All that's assuming you meant 51, not 41. And although 51 can be AC related it has nothing to do with you not having AC.

Thanks for clearifying
Will be replacing tps this weekend

My recent code was 51...I just rechecked it
