Default would it be worth it to get a tune for 1.6 rockers

Hey guys would it be worth it to get a tune for the 1.6 roller rocker i just installed? the reason i ask is that i am racing in an actual event called west coast and want to make sure there will be no probelms with the 1.6 rockers and 125 shot i plan to spray. I use a manual timing retart so i can take more timing out if needed.

I dunno about the rockers but I would tune it to run more efficiently on the nitrous.

W/o that cam in your sig? I wouldn't bother getting it retuned. Now, if it's not tuned for the cam OR the 1.6s, and the cam is installed, you'd probably pick up 10-15hp from just the tune (again assuming the cam is in and not tuned for).

Yea i i just have the 1.6 roller rockers on right now. I do not plan on putting the cam in until afetr the race on april 4. I figured since the n20 was a wet shot and i have a way of retarding timing i should be ok right?????
