We start to having problems with this setup(GT3076 Twinscrool) after change OEM intake manifold to aftermarket https://lh6.googleusercontent.com/_cS5zg_csl3A/TaiyBwCK3sI/AAAAAAAAB3M/L51XBRhLHxc/s640/DSC00791.JPG and finally come up with this and car is working perfect https://lh6.googleusercontent....

Here's a quick pic

I just replace and reposition the TPS. It seem to be working perfectly normal now, no jump or weird spike, but my original problem still remain, every time I gas the car pass 3-4k rpm the cars bog down dies if I don't catch it fast enough. I have no idea what to do now, any more suggestion?

on the stock throttle body the fast idle cam will make the voltage change.. tps adjustments should only be done when engine is at operating temp ~ 80 deg.. I did as Matt suggested, and the TPS voltage was just jumpng all over the place even when the engine is off and we are just sitting there doing...

Is the TPS working correctly? (home position, voltage output etc) im going to try to reposition the TPS today Does the ECU perform Fuel Cut as expected in reference to the fuel cut tables? Yes Does the exhaust reading from the o2 sensor display a lean condition when you close throttle? Yes Is the id...

Yes

I just got done tuning my car and everything seem to run right expect for the fact that when I let go of the gas too fast the car die, does anyone know how I can fix this issue...

I got the base tune setup, however, I ran into another problem. I can't figure out how to log the fuel trim to check for short and long term effects afterwards. So I'm just wondering if logging the fuel trim is even an option for Nistune and if so can someone show me how to do it?

I'm sorry, it's an S14 Sr20det

The drive from my current shop to a nistune workshop is about 25-30 miles aways and I have tried using a base tune by changing the operation of my injectors and MAF, but it doesn't look like this will be enough to get me to the workshop. I was hoping that someone here would help me out give me a bas...
