How much for a 2008 gen 4 Silverado? Turbo 5.3 have a single racetronix hitwire kit but not installed running low boost in stock flex pump right now. Want to run a single 450 or a 525 to get about 6-700hp pump gas. Single 8an feed to stock return after market boost ref reg after market rails is the plan. 80# deka injectors. Products looks and sounds nice and easy to install but iam curious about the 1/4 tank starvation issues. Haven’t taken the stock bucket out yet. Do you supply the bucket any warranty?

 

i nee done for my 04 what 340 pump?
