Progress Thread Bolt On Improvements

[My 03 GT]

Have a stock 2003 GT looking to do bolt on improvements.
SR Performance CAI & 70mm Throttle Body w/ Intake Plenum vs
BBK 1780 78mm Throttle Intake and
BBK 1718 Cold Air Intake System?
Steeda Underdrive Pulleys vs
BBK 1559 Underdrive Pulley Kit?
Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes vs
SCT 7015 X4 Power Flash Programmer?
Any suggestions would be great. Thank You. Have a stock 2003 GT looking to do bolt on improvements.

Headers (long tubes), gears and a tune go a long way. Skip the underdrives. Cold air is worth minimal gains but I like how they look better (personal preference). Go with a JLT vs bbk. The plastic of the jlt won't heat soak like the metal bbk.

Don't do canned tunes from bama. Go to a reputable tuner AFTER all your mods are complete. Buy one at a time and save them up for all in one install if needed.

A set of cams will really wake up a pi motor as well but things start getting costly then.

Better gearing if you have not done it yet, you didn't mention stick or auto.

Stick.

No mods.

Like stated above.

Under drives are a waste of time and money. Do not buy a canned tune they suck, go to a reputable tune shop after you have installed your mods.

Headers, gears, tune.....

The intake is nice but without cams it's a waste of time. The benefit would be nominal.
