No not at all,like i posted before they were just installed and a dialed the fuel pressure back to half ass tune the truck,I can tell you one thing it could be my imaganation but it seemed like the motor got louder,Datrod came by and he said it sounded good,But a retune is in the works and hope nothing else goes wrong,if i get 150 plus HP at the wheels i am fine with that,because then the motor would be at about 175-180 crank and thats more then stock.
And just a Tanker disclaimer,i knew when i got this FJ that i was going out on a limb not really going through the FJ based on the info i got,With that said if it takes a shit then no problem the motor was designed to almost walk out of there and it will get redone,so what ever happens happens.
