The tune on the other hand you should care if it gives the advertised HP and that also costs a lot more.

Anyway do what you want.

I agree - I have my feb speed pipes going in on wend am - I did not want to tackle that project on my back in my driveway - one of those nuts is really hard to get to and I think I would have to come in from the top with a long extension and wobble socket - plus all the studs look really rusted - better to leave it to a real mechanic working on a lift

I am excited to hear how it sounds and feels after that

I will be flushing a load of 93 octane on wend night LOL

Tuscani66 is infamous around these parts

I have a stock 08 CTT and considering the IPD upgrade and have an AWD dyno nearby; if I find a good deal on one, I'll pick it up and gladly do a before and after.

I will also order the 2nd Cat Delete piping. Because of the ease of changing the Cat Delete piping, I might do a before and after on that on stock as well.

Biggest factor at the moment is my large wheels, I'll find OEM set to put on prior to DYNO runs. No promises on time/when but is a plan. I make it a habit do those things to all my cars haha.
