93 stock MAF. I have my injectors replaced with 24# (ford racing) and TB is 70 MM. Cobra intake, GT-40 X heads, B cam.

Do I need to replace the harness as well ? or it should work fine?



I run through many troubles since I had these mods.. I installed PRO-M MAF calibrated for my mods, after few months, I added TwEECer tune , but nothing seems to work togather.. the car is always locking the power it should give and it hesitates alot when you accelerate !



Any ideas on this swap with 93 stock parts?

You need a 1993 cobra MAF to use that EEC, in addition to 24# injectors you already have

Ok , so that's the cobra 93 stock MAF , right?
Do I need to change the main harness ?? or 90's harness will just work fine?

The plug is the same. The wiring, ultimately, is the same.

All you need to do is plug in the EEC, the MAF, and use 24#ers and good to go
