its noticeable but not like a mustang. the delta flow mufflers are quiet but you can still here it coming down the street. it has the sound of a v8 just a quiet one the resonator is what makes the car sound better. seemed like had a noticeable difference off the line and just easier flowing up top. prob will make more of a difference after i unplug my cats

Any Boring will require a new bigger Throttle plate, where to find one, I don't know.

Hmmmm I've been talkin with a few other people on here and they seem to have the same opinion as me: the TQ looks good but something just ain't right with the HP there man... according to that you've only gained 5 or so HP at the crank from stock... and that can NOT be. Maybe rancher can post again on the subject, or SD even.

What is Halfshaft??

What does that mean?? If there's a gain in power I'd like to do it, but don't know what it means??

DAMN your RWTQ is high You have about 20-25ft-lbs. over stock but LITTLE to NO gain in HP

STOCK is about 115-120rwhp and around 190 rwtq

On though the comes to mind "was the torque converter locked for the dyno pull?"
If you torque converter was lock you would loose torque but gain HP. with you mods I would say you SHOULD be around 130rwhp and 200rwtq
