Hey everyone my mate is getting a new TBE installed on saturday..Just wondering does he need a tune or can he leave it without tuning.. He has My00 wrx

Thanks

search mate!!! will save you getting flamed

no tune required, but he will get more performance out of it if he does

if you want to get full potential u would have it tuned...

search button is good

Will be running rich i reckon, maybe a bit of boost spike too. Best to get tuned afterwards for sure.

I ran my 01 with a TBE untuned, made fuck all performance difference. 120kw with a TBE, intake, etc etc .. 160kw when the tune went on, go figure.

Might as well put a different turbz/injectors on at the same time then go for a tune and crack 200kw.

GC8s handle mods better than MY01 onwards without tunes

x2. If it has the stock ECU, then put it on and drive away. As far
as I know you won't get any more power, just peak power sooner.
