Astrak Posted September 7, 2006 Report Share Posted September 7, 2006 How well does the fastchip work for the 4.9 engine, is there a substantial notice in acceleration? Also how does the fastchip install does it replace the calpak? Is it easily installed? Link to comment Share on other sites More sharing options...
Ed Hall Posted September 7, 2006 Report Share Posted September 7, 2006 The Fastchip is an expensive way to advance the timing a few degrees. You can get the same effect by advancing the timing a few degrees on the distributer. Yes, you'll gain some power but it'll ping more. Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted September 7, 2006 Report Share Posted September 7, 2006 I felt the fastchip helped the performance of my 4.9L, subjectively. Unfortuately, I got the gtech/pro after the fastchip. Installation is simple, just pull down the PCM then swap out the chip.
