Antihero1981 8 Posted December 16, 2008 Report Share Posted December 16, 2008 Hi , do you need to remap again if you go from stage 2 to stage 3? or can i just change the pulley and belt?who sells the belts for the v9?thanks Link to post Share on other sites
Kelster 0 Posted December 17, 2008 Report Share Posted December 17, 2008 By changing the pulley you will increase the boost therefore you will need to remap the ECU as it will not be able to compensate on its own. NS racing, Stealth or Storm should be able to sort you out a belt. Link to post Share on other sites
rodney 17 Posted December 17, 2008 Report Share Posted December 17, 2008 yes as the mixtures all change... (more air than you had before). NS Racing also and I think Regal might.... have the belts Link to post Share on other sites

wayne_1@tiscali.co.uk 27 Posted December 17, 2008 Report Share Posted December 17, 2008 belts r the same for stage 2 or 3 all u need is 12 psi pulley and idle bracket is diferent to stage 2 as th e pulley wheel sits behind alternator rather than at the front of it Link to post Share on other sites
