For anyone to be able to send you an e-mail, we would need you to add an e-mail address to your profile (not in the forum itself, as the software for this forum [properly imho] strips out properly formed URLs and e-mail addresses. One of the reasons for this, is to slow down spammers who would use software to harvest e-mails for "spear phishing").
AND for much better opinions of what your truck needs, include the serial number, and in your case, is the motor a 4y-ecs or what series emission controls you have, (the truck info you can put in the forum) Thanx
