If anyone from TSP help me out here? I want to tune a basic bolt on 01 z28 and plan to install injectors and a racetronix fuel pump, it will be a mail in order tune please chime in if you're here


I want to see if I will loose mpg if i install bigger injectors? what are the possible gains from just this?


Thanks

If it's just a bolt-ons car, leave the injectors alone. I'd say the same about the fuel pump unless the factory one is going bad. The factory fuel system (pump, rails, injectors) can easily handle 380~390rwhp. No need to change that stuff out until you go with a bigger cam, heads, or something major like a nitrous kit or power adder.

Well, my suggestion still stands. You're not going to want to drive the car without a new tune when you move to a turbo setup. So, might as well tune it all at once.
