I would not make any dyno pulls until you figure out why you are losing over 200hp on the top end. New programming will not fix this. You are losing fuel pressure or some other major element to lose that much power. You are down over 100hp from a stock C55. Too much ignition advance from programming will likely not cause this. Run 100 octane minimum as a precaution and good luck.

I have been using this formula for the past 15 years. Combined with going to the drags for 17 years and having Dynojet in the shop for the last 8 years. I can pretty much vouch for it's accuracy. It is not as good as a dyno, but it will get you in the +/- 5% range.
Plug in several cars from the back of major magazines and you will keep this formula in your head forever.

The car is currenlty running ok at 390rwhp. I have 30 hp missing and it has to do with the programming. Aside from that it has all been taking care off.
RENNTech has been real supportive! So I am keeping the car and as soon as the new program is in I will have a new dyno and a date with Dragon
I raced an 03 Z06 - no problem at all - I was about 2 car lengths a head till 60...
Also raced a brand new EVO the other night - by 80 mph I was like 25 cars a head of him... :v I promise to keep everyone posted.
