Engine 95 gt h/c/i questions.

I am about to install trick flow twisted wedge heads, holley systemax intake, bbk shorty headers, 70mm throttle body and a trick flowvstage 1 cam in my car. Should i also go with 24lb injectors or would the 19's be ok for now. I know if i do go to 24's a different tune would be ideal but would i be ok with a calibrated maf?

I'd go with the 24 lbs. injectors, personally, just so you have some extra "insurance" if you plan on doing some more mods. down the road, and so you have more fuel and do not risk running to lean.

Would i need a bigger fuel pump if i went with 24's? Also do you know if a tune is absolutely necessary with this setup or would a maf calibrated for 24lb injectors be ok?

A 255LPH pump is going to mandatory after all that. I tried to get away with 19's after my H/C/I install and I had lean problems. I then changed to 24's with matching Pro-M 77MM Meter and made a huge difference on the dyno.
