Drag Strip tips and advice needed.

I have a full exhaust after the sensor. The tuner did notice it and I thought I fixed it with a new one to clamp on. Nope. Welding is a must.
It is a regular throttle cable. It just needs to be adjusted.
Yes the EFI doe have a map sensor and O2 sensor that it uses to properly mix the fuel.
Time to fix a few things.
Thanks for all the help.
