how much before you have to chip it

I have a 90 5 speed.
Bought the car with new parts never installed so now they are on and just need to know if it is going to need to be chipped or tuned. I know it will only help but does it NEED to be done to keep from hurting anything?
15% sc and jc pulley kit, griffin radiator, mag power front mount IC, full flow master exhaust cat delete, raised blower hat,cobra mass air,255 fuel pump.
Thanks,
Mike
 
well

With 15% overdrive, you're getting the boost pressures really high. With that, the amount of fuel needed to get the right air/fuel ratio is critical for detenation prevention.

The stock injectors for a 90 are 30lb. 94-95 with more boost and more flow use 36 lb. You also have a small MAF which doesn't help


My guess is you are maxing out your stock injectors right now.

With more air, you need more fuel, a bigger fuel pump does just that (is capable of pumping more fuel) not getting more to the cylinders, that's the job of the injector.

Look into gettting it tuned for just safety
