Can another 5-10 bucks a week have that much of an impact? Especially considering the OP said he drives his car 4k miles a year (so figure maybe one fill up every three weeks or so for him...). [&:]

 

^^ Very true.

I'm so psyched to get this thing on the dyno. I had another mustang I used to have put on a ****ty mustang dyno, so I'm really ready to see the real thing for once!

 

Got the final install price and tuning price in today, $675 all said and done. Did a pre-mods dyno run and she put down 227rwhp, so I'm just hoping for 30rwhp with the headers, mid pipe, and 93 octane tuning.Will let you all know tomorrow night
