183.5 hp

That's what I did before an unfortunate accident with a telephone pole.

Too lazy to add up the pricing.

I'd bet you or anybody $20 in a back to back dyno test on a stock 2.5 that your optimized TB and Secondaries won't do crap for a significant power increase.
Significant is defined as something larger than the run-to-run variation in power ratings on any standard dynojet dyno. i.e. more than 2 HP (and that's actually generous to you since variation between runs is known to be higher at times)

To prove this, you would need two runs to give a semi-accurate baseline, change to your optimized parts, then do two more runs.

Putting time and money into optimizing TB and secondaries....LAST thing I'd put effort into since it would yield the lowest return, if any.

Yeah.. I doubt it did much but that's what I had done when I dyno'd that number so...
