Truthfully who.....
by "performance", I assume you mean straight line performance. in that case, ive put about 3500-4K into mine, but the motor itself is mostly stock. and i have nearly 80% more power than stock. my QT have gone from 16.68 to about 14.8-15.2 give or take. i havent ran it yet with the newest motor. but its a blast to drive on the street, and well worth the money ive spent. esp since im just getting started
