Needs A Turbo
ok guys im running e85 on a 3.2 and supporting mods i have no kr on 18* of timing.....but at the top of 2nd my set 11.5 afr climbs to 13 and i lean out and knock like crazy.....so besides a fuel filter will a fuel pump rewire fix this since im on stockwiring with a new stock pump. lemme know what u think b4 i get the 70$ casper kit!
 


Rewire will help forsure.whats your injector duty cycle hitting what size injectors?. Post a scan. Might need to add some in the rpm vs time table
 
i already have #65's and i dont know how to post a scan im not the tuner my friend is......my tuner doesnt think i should need a bigger pump but ill try the rewire first hopefully that cures it. or maybe its my cheapo ebay stock pump :(

isnt the caspers rewire and prj rewire the same?
 


the PRJ rewire is beefier, but they do the same thing. also if you know what youre doing you can do the rewire for way less than buying a 'kit'.
 
Id bet your pump isnt keeping up. Thats alot of fuel demand. Rewire MIGHT work, but I think you are past the stock units output. Only way to know is with scaning
 
i went with a prj rewire, the fact that it doesnt lean out everytime makes me think its insufficient voltage to the pump as voltage can be intermittently higher.
