if you want to play it safe just buy a set of the budget friendly downpipes for $300-$400 and then run the E30 map safely
Yea I plan on doing so but want to try and get my turbos replaced under warranty (slight wastegate rattle) before bolting on downpipes. I'll probably try an e30 map and get some logs. If not I will try stage 2+ with the additional octane. Just as long as the logs are good and the car is happy I am happy. O, and even happier if i am faster than an isf. Hehe
