help! still breaking up

[N2HIPSI]

lowered the fp to 42#. still breaking up at higher rpms. I mean the car noses over like i let out of the throttle and the turbo sneezes back thru the filter. I tried a Jay Carter street chip instead of the max effort chip. i think it could be my cam sensor. It is installed with the wires in the cap coming out at 11:00 o'clock instead of 5:00 o'clock. I used a cam sensor tool and the lights are green which means the window is lined up correctly. Does the direction of these wires matter, if the tool says it is set correctly and does this have any effect on higher rpm breakdown?
Also, does anyone out there with an Art Carr non-lockup converter have a stalling problem when you let out of the gas?

What are u using for a scan tool. It sounds like too much boost and the car is pulling timing. For the stalling issue, it sounds like your IAC may be out of whack. Did you set the IAC per Steve Yanklins instructions that came with the thumbwheel chip?

Cam sensor tool

Just because the tool lite is on does not mean the sensor is in correctly.
It will light at any time the window is lined up. The sensor could be anywhere in the 360* rotation.
The key is for the engine to be 25* AFTER TOP DEAD CTR on the COMPRESSION stroke. If it's in 180* out, the lite will come on and the engine will run like crap.
If it's set w/ the crank in the right position, and the lite is on, it does not make any difference where the wires are. The location of the wires is a function of where the body was dropped into the cam gear at.
If it's in 180* out, the injectors still fire, but the fuel puddles on the valves and makes for some nasty performance.

HTH,

only getting to 12-15lbs of boost before it falls on its face. i am not using the max effort right now.

A scan tool would really help you with the stalling, it's probably the IAC/minimum air needs adjustment,, or there is an intake air leak somewhere.

Also, what injectors do you have, and is the fuel psi going up evenly with the boost? Perhaps it's running out of injector, or the regulator is bad.

just a shot in the dark- my car did something like this when the ram air hose would collapse under boost

real weak valve springs? fuel pressure dropping? vacuum hose on the fp reg? 1lb FP per PSI of boost?

You need someone to "patch" your chip for the NonLU anti stall.
