Tuning this badboy?

[Tom]

Well bit more of an update on this just because people are stupid... He said the truck was smoking loads and had to turn it back lol it was the very lightest whisp on full chat so straight away i thought here we go. He then took it to his garage that fixes his truck and they told him that the way i tuned it was wrong and that i could of blown it up.. so i said ah right yeh whatever whats there method of tuning then soo he says to me the diaphram mate and and then blahblahblah turns out all they do is take the lda cap of and turn the lda but they dont even take it out they just turn the black bit and drive it then do the same til they think its better.. i said that wont make it any more powerful but nonnononono there mechanics not me im wrong -.- Stupid prick /rant over
