I saw a post on another forum with the idea. So what's yours? I'll start!

Competition Stage 3 clutch - lasted 10,000 miles, DD no launching
Lightweight Flywheel - makes DD'ing a tad more difficult
Cobb AP - High cost, low functionality
Prosport Wideband + Boost - very difficult to log with
eBay catch can - Have DrivenFab v3 now

 

Not getting Ralliart mods while they were readily available.

 

1) getting a BBX Light instead of going straight to the 7670 1.05 with Ex Waste Gates from the get go
2) getting the AEM combo boost and AFR Gauge
3) Not going to Moore Automotive right away instead of trying other closer shops first

 

Not burying that hooker deep enough.

 

Installing solid driveshaft carrier bushings.


Now I'm not sure where all the old bushing parts went, and I'm really just too lazy to switch back anyway.

 

I love this thread already... I am just starting to mod, i will have some regrets down the road but for right now i am scheduled for a tune Aug 5th. So i am getting everything i need before the tune!

 

I don't regret a thing, but my bank account regrets me.

 

I still don't get why people complain about the Cobb AP.

It has been plenty functional for me.

 

It's nothing against the AP, but when you spend $450 on something that has less functionality as something that cost $170 then you realize what you could have bought in the first place.

 

what I'm saying is that there are other functions that AP has.

You don't have to carry a laptop around for logging, I have used the valet/anti theft mode many times, you can flip maps on the fly for road trips where you may not find the correct octane.

I have never used the cable so I don't know if you can do all this with the cable as well. I know the cable is the go to for tuning but that is really a moot point for most street cars as most can be tuned on the AP as well.

 

That is true, those are some nice functions. I mean I had an AP before, the reason I sold it was because you can only datalog on Wideband's that are defined through a formula, so still not completely accurate (nothing like serial logging). But the tactrix lets you apply ECU patches, load Tephra mod and you can log more parameters in EvoScan or define new ones if need be. And yes the AP comes with OTS maps, but they're generic even if you were to use exclusively Cobb parts because they need to accommodate different altitudes/temps. So ideally you would need a dyno tune anyway.

 

off topic but, ^^^ what costs $170 thats more functional than the AP?

 

No doubt about the dyno tuning. When I picked up my AP, I didn't buy it for the OTS maps after reading all the reviews on them. I bought one for the convenience mostly. I did try them out though out of pure curiosity lol.

Tactrix cable is definitely great if you get seriously down to the nitty griddy tuning to maximize what it has to offer.
