okay so here are my mods header,high flow cat,2.5 exhaust,9.3 plug wires, and i just put on a adjustable fuel pressure regulator. so now i have some 450cc injecters but i dont know if my teg can handle them without chiping the ecu? Also does anyone know how many cc's stock 90 ls teg injecters are? any help would be great thanxxx

 

You don't need larger injectors with a basic bolt-on setup. You will not gain any power, even if you have the ECU set up to run injectors that large over stock 240cc injectors.

 

i heard if i raise my fuel presure higher than 10 psi above stock it will over load my stock injecters. i just wanna know if the 450's will foul out my plugs or what not

 

You don't need injectors or a fuel pressure regulator. Stop trying to mess with the fuel on a stock engine...it is already set up for optimum power and gas mileage. Trust me, the stock injectors have more than enough fuel for most future upgrades except fully built N/A or forced induction.
