Well I dropped the ball. Last week I went and got my dyno tune at Speedfactory. It didn't go well to say the least. I had the wrong spark plugs in (need colder ones for turbo. whoops), the TPS was torqued down incorrectly (I didn't even know sensors had torque specs), and was a bit too high on oil level (didn't change it on a level surface. No biggie, right?) Just getting these minor inconveniences fixed definitely put more of a dent into the total price ($550). After all those mistakes were caught I definitely felt like an incompetent mechanic in the presence of these top notch tuners. He said that I wasn't even that bad, and it takes an hour or two on average before cars usually touch the dyno.
So my car is finally loaded onto the DynaPack, which I noticed was made in New Zealand (odd). After taking a couple pulls and tuning the partial throttle AFRs, I was told that the camshafts were too big for this set-up. The car wasn't creating enough back pressure for the big camshafts, and resulted in the horsepower dropping from its original 325 to a measly 280. Vtec is now set at 7k. It ran a lot better than before, but it still isn't right.
So now I have to replace my Bisimoto 2.4 cams (for sale afterwards), and replace them with GSR cams. I am going to have the pros at Speedfactory do it sometime after the holidays, because I don't want it messed up by myself. Really been kicking myself in the ass over my tune day. Today I have to replace the alternator on my 81 Subaru wagon, so successfully completing that easy job will be a nice little confidence booster at least.
tl;dr cams too big, lost 45hp
