I have a 2008 Silverado 1500 with a 5.3 and the new TVS1900 Magna. Right now I am running the stock 3.7" Pulley and am going down to the 3.3". In about a week I am going to get the truck dyno tuned and was woundering if you guys think I should put JBA Shorty hearders on before I tune it? Would I gain that much? I am also running Flowmaster Super 40's with stock cat's.

Thanks a million

I will post Dyno numbers after the deed is done

I think you will see minimal gains with the shorties.

I can't find anyone that makes long tube headers for the new body style Silverado 1500. You guys know anyone?

Thanks
