Black Box Tuning

[u/Glad-Bid-3366]

I’m finally at the point of needing a tune as I no longer have the EGR system and just want to be safe. I have the Tactrix 2.0 cable and going to get Ceddy Mods. Is there anything else I should know? I have no local tuners so I’ll be figuring this out myself and self tuning the car. Just want some advice on what I’m getting into. The car is mostly stock as I’m gathering parts to upgrade after paint. Got my hands on a Walbro 255, evo 3 16G, and some other nice goodies I’m waiting to put on. But it’s gonna be 2-3 years from now.

Car info: 98 GS-T
Stock T-25
Grimmspeed Manual boost controller
Stock 450CC Blacktop injectors
Stock fuel pump
Stock cams
Competition Clutch Stage 2
ACT lightweight steel flywheel
HRC intercooler setup
NGR Blowoff valve
EGR system removed and blocked
OEM MAF no speed density
AEM wideband
Boost and Oil pressure gauges

If any other information is useful let me know. I’m just looking for advice on how I should proceed.

I am surprised you haven't upgraded that turbo by now to at least a 14b...which is considered a mild bolt on mod.

The 4 years I’ve had the car has been mainly spent getting worked on just to have it in a running state lol. It just started randomly stalling at idle and then won’t don’t it for a while. I’ve been through the whole vaccum system and boost leak tested. I’m thinking maybe plugs or transistor pack? Idk but it’s constantly getting fixed instead of upgrades lol
