don't listen to uncle meathead his opinions are always negative. Accufabs t/body is a first class piece! Plus it makes power ! mac's mass air system doesn't trick computor either. fact is mac & accufab work very well together. I'll post West tech's dyno with both parts with afr & gains Will get someone to scan them in very soon. Dyno was done on my brothers 2003 Cobra very impressive.Yes and he is installing MAC ceramic coated long tubes this week.I'm sure meathead will be negative on accufab & mac even with dyno test & afr's posted edited by staff This is your warning, continue with the personal attacks and you'll receive a nice "timeout." Please review Stangnet's forum guidelines if you must. If you feel like continuing the urinating contest without doing so in a respectful manner, take it up via PMs or e-mails, not on the msg board! The end.
