O.K.- so about three months ago I dyno'd my 2004 Mach 1 when it was bone stock except for a SLP catback and was pleased to get 283rwhp and 310lb/ft.
Today I had it dyno'd again- this time it has the SLP catback, a Magnaflow off-road Xpipe, a PHP intake spacer and a Diablo Predator Handheld Tune installed...
I was hoping for 295rwhp or so- and was extremely unhappy to get back only 284rwhp and the torque went down to only 300??? WTF??
Does anyone have any idea or advice as to why this could of happened? How could I have only gained 1rwhp and lost 10lb/ft.????
Any and all suggestions/advice is greatly- GREATLY appreciated!!
