Ok I Think I have read every post on this site, Got some good ideas I do have a few questions about what shift kit to buy. Keep in mind my maine goal is to be able to get ride of the TM 100% when I get my tune. I allready have the Corvette servo, longer pin & 4th gear billet servo. IMO The shifts are just perfect for me. I am going to order a shift kit ASAP. But witch one? Can I just do the Correction kit (SK) and buy the 490 boost valve, Or is it vital I buy the HD kit. I dont mind the extra $50 for the HD kit as I know it will cost alot more if I make the wrong desicion. But do I need it?
