85lbs are a massive injector for what you are talking about...

80-85lb injector have not so **** hot idle characteristics due to you cannot close them long enough, their spray pattern sucks at idle as well. They will support 1300rwhp in an LS1 based boosted combo

60lb seimens I have made 700rwhp with them. Many others in the 8-900rwhp range.

35-40lb injectors sound like what you are looking for. Factory injector is fine.
