My 94 ls has 140,000 miles on it, I have AEm full cold air intake, Tsudo headers, high flow cat and catback exhaust, 10.3 mm wires for a prelude, and Iradium plugs, I get only 230-240 miles per full tank, is this normal???

same here i get close to that also with a FULL tank with my p72 ecu.
however i only get ~250-280 on my chipped p28.
big difference.

 

280-320 city

400 if its all highway.

Correct me if im wrong, but arnt the RS tanks like 10 gallons, and all other tanks are 11.

 

300 miles to the tank on the highway .. but im boosted. maybe 200 miles stop and go driving.

 

My gas gauge gets close to empty around 250 miles, but I know I have like 2 more gallons left. Are you sure your gauge isn't just reading incorrectly?
