i am going nuts over here i thought the dynolog should be 10% or more lower than the dynojet i can only see 12WHP almost 4.5% is that rite ??? or have we been

loudandheard

I have heard that a dyno could vary as much as +/-15hp on the same day and especially on different dynos. Maybe try doing some thing more drastic such as headers, you already have various baseline dynos. I'm surprised your exhaust did not yield more HP.

LawRens

dynolog is VERY conservative on their numbers. Be proud, 285 is excellent. my c43 on dynolog got bad numbers... so bad i'm not even going to post it... LOL.

the headers are in the pipeline just waiting to confirm the tune and who is doing it also i will change the X-pipe i have to one that is better flowing

** FWIW, this is about what a stock C55 does/should do on a Dynojet!! *** I've seen it before at Chicago Performance and this is pretty typical. I've seen from RWP 280-295 from a stock C55 with no mods.
