Much Props to BUNTA for performing internal dual cell conversions and PCB swaps on my cars. Over the past month he has installed dual/triple cells and/or 2 speed PCB's on my LXXs, Tomy Bit Boosters, MS PRO's and ZZ's with no problems. Each car, runs like a rocket and was done at a good price. Cool guy, very honest and straight up. I deal with him all the time. Shipping is always quick too.
