I'm going to install my Jet Hot long tubes this weekend and I was wondering if I should just buy an LT4 Knock module now assuming I will need it or wait? Will it be needed or should I wait and scan for knock retard? If so where do I purchase one?

Thanks
Sean

 

might as well go ahead and get it now...........i got mine from jason cromer, shipped it to me for relatively cheap.........do a search for his phone number, he works at a dealership and gives special pricing to forum members.

 

do a search for my posts i asked this ? a couple weeks ago ordered mine from gmpartsdirect.com search and find the part number
