-do you not have access to 93 octane?
-ok you may have run files from experienced tuners... but if they didnt have access to good data then you wont get a good file.
-DHP 1.5 settings are nothing but a starting ground if anyone were to just try and run them you would just be asking for problems.

all we asked was for a good data log and bin so we could look things over for you. i just feel you threw in the towel too soon and didnt give us a chance to help.

it may very well be that your engine just cant handle a 3.5 without more mods. either way more mods wont be a bad idea for it anyway... since your having issues tuning it, its best you build it so you can safely tune it yourself.
