Not sure but low voltage makes thing go crazy. Start with testing battery and alternator?

These models have a history of bad ground wires/connections where the battery ground attaches to chassis

Hello all,
I own a 99 2 door hoe LT. It has 98,000 miles and I've had it for 6 years as my daily driver. I just bought a new car and have finally made my hoe a project car (since I will be buried in it). Looking for some advise on what mods I should do.

What I have done:
K&N cold air intake
Superchip
replaced front rotors, calipers, lines, mc.
replaced rear drums and lines
replaced wheel bearings, most bushings, and tie rods
replaced OEM shocks with new OEM shocks
New water pump
New head lights and tail lights

What I want to do:
switch from the CSFI to an MPFI
New exhaust from headers back (open to suggestions)
She's a bit ugly and needs a new paint or at least a new clear coat
head unit (I have Boston acoustic fronts and a JBL woofer, from my brothers 97 Yukon (rip))


I don't want to supercharge or turbo (not yet at least) but would like some recommendations for performance mods.

Thanks!
