I am noticing (as well as some of my friends at the track) that my car is just stumbling off of the line and bogging pretty bad. I know my car is running really rich (almost to the point that it will burn your eyes if sat running long enough) and that my timing may be off since the HSR swap. The car feels pretty weak during the early part of acceleration (3000 and below), and then picks up in the higher RPMs. It is just odd that the car is running slower with HSR and full exhaust than it did when the car was stock. Any thoughts to my bogging issues? Also, this is being done on a stock chip.

 

Your proboly running to much fuel pressure or timing. try backing them off just alittle.
