I'm wondering the pros/cons to these two options.

Obviously the ideal scenario would be to get the 380cc injectors and an actual tune, but given I'm not made of money, would it be worth just getting a tune with my existing upgrades in my signature or would I really need the injectors anyway to get decent gains out of a tune?

It seems like some dealerships will load on the JCW software for cheap, too, so I'm wondering if I got the injectors would the JCW flash give me any increase in power until I can afford the tune at some point?

Just looking to you guys for opinions, considerations etc. Thanks.

 

With your mods the ECU will self adjust to the 380's, so you could install them whenever you want, then if you can get a cheap install from a dealer go for it, (yes it will help) if not just save up & wait for a custom tune.

 

I had similar mods. 15%, JCW intake and injectors with the jcw tune. I went from 184 whp to 189 whp with custom tune. YMMV.

 

I figured a custom tune would have pulled way more than 5 whp. Is that normal?

 

Yes & No, first off it was already running the JCW tune which, with those Mods would have already made an inprovement over stock, plus you have to look at what a tune really is, nothing more than adjustments to make your parts work as efficient as possible, and since every car is different, it's "Base Efficiency" also will vary.

Just as an example, look at where it started, 184 is actually pretty good to begin with, my stock JCW car only Base Dyno'd @ 165whp, so in my case there was a lot more room for improvement.

 

Could not have said it better myself. I was lucky.
If have you these mods, on a budget, and access to the jcw tune for cheap. I would go this way.

If you want more efficiency, and want to get rid of flat spots and improve drivability, go with a custom tune.

 

anyone know if i can upgrade or flash my ecu with a jcw tune using a gt1 software? (anyone know how to do it)

 

Is it true that some dealers will flash the JCW for the cost of 1 hr labor?
