MAF sensors are extremely sensitive. So sensitive that I can't even begin to illustrate it to you. You should endeavor to replicate the EXACT conditions of a factory intake and MAF sensor as much as possible...... The ECU has a VERY CAREFULLY defined MAF sensor scaling table. ANY changes to the filter box, bends near the MAF, or the MAF housing itself WILL result in incorrect and non-linear scaling. The ECU on a '93 is not capable of flash programming and thus not capable of ANY adjustments for MAF scaling. You will ALWAYS be best served by EXACTLY replicating the factory intake and it's air filter. Make sure all connections are clean and tight. There is NO PERFORMACE to be had without tuning of the MAF scaling. Which is not possible without a stand-alone ECU. LINK ecu does make a plug-and-play compatible ECU for this application. It is speed density and you can toss that manufacturer specific MAF and it's housing. GD

pretend there is an egg, that must not be broken, between the top of the gas pedal and the bottom of your right shoe.

lol, you dont necessarily need to drive like Grandma, but you do need to chill just a little. make an effort to slow down a little.. for a couple of reasons.. 1. your fuel mileage will increase, and 2. you wont end up getting ticketed when pulling away from a stop, dont stomp on it, just ease into it - you are not at the drag races, so stop pretending you are. there are no prizes on the streets, only tickets. I live in the country, so for me, backing off the throttle before i get close to a stop sign is quite useful.. about a 1/8 mile or so.. let the car slow down a little before using the brakes.. brakes will last longer. it is not about driving like Grandma, but it is about making multiple small changes that do add up.

Gonna set a goal to hit 300.. I just can't stand driving like grandma.

yup, that right there is your problem. You should be able to get closer to 300 miles to a tank full... (roughly 10.5-11 gals of the 14 gal tank) I am going to guess you are under 25 yrs old, right? driving like that is not doing your car any favors - wearing things out faster. Sure, it can be fun - in the right setting - but daily driving on city streets, not so much.
