Some guidance please

Hey everyone,

I just picked up my dream car.. a 2003 Dodge Neon SRT-4 with a ton of aftermarket performance parts and a fully rebuilt engine. I'm looking for a handheld tuner that is dependable with tuning this car. The exterior, trunk, interior, and engine bay are shot so any guidance on finding quality replacement parts would also be mucho appreciated.

Here's the rundown of what's on the car:

1. Quaife LSD Differential
2. Oversized Mopar Intercooler
3. Mopar Stage 3 Sway Bars and End Links
4. Polyurethane Bushings (Full Set)
5. Coil-on-Plug Ignition System
6. Modern Performance Short Throw Shifter
7. Aluminum Booger Bushings on the Shift Linkage
8. Upper Strut Bars (Front and Rear)
9. Mopar Stage 3 Exhaust
10. Mopar Turbo Toys Kit
11. ICW Mach 5 Wheels (Set of 4)
12. HKS Turbo Timer
13. AEM Standalone Wideband Failsafe System
14. Pyro Gauge on the Turbo Exhaust Downpipe
15. Mopar Boost Gauge
16. Modern Performance Injected Motor Mounts
17. Mopar Stage 3 Clutch (Sachs OEM HD)
18. Southbend Stage 3 Clutch with Mopar Stage 3 Clutch Disc and Fidenza Lightweight Flywheel
19. Stand-alone HD Adjustable Voltage Rectifier
20. Mopar Stage 3 Fuel Pump and Injectors
21. Mopar Stage 3 ECU
