A few weeks ago I posted a relatively strong and consistent baseline run on a DynoJet at a local shop here. The car made 372hp and 358ft/lb. So I was pretty pumped to see what the car would do on the dyno with the 91 Bama X4 sport tune loaded supporting the recently installed JLT CAI and Magnaflow Street 3" cat-back.
To my absolute shock and disgust, the car lost power! 362hp and 350hp! 10hp and 8ft/lbs less! Also, keep in mind that I kept the re-test as consistent as possible, again using Shell V-power and the same shop, operator and DynoJet as before.
Both myself and the operator assumed something definitely was wrong, so we decided to re-flash the Bama 91 Sport tune and let the car rest for a while, Maybe excess heat!? Why the lost 10hp!?
The best the car did was 369hp and 355ft/lbs, still 3hp and 3ft/lbs shy of the completely stock setup!
Anyone have any thoughts?! I'm at a loss here. I'm going to call Bama tomorrow to see how this can even be possible. I'm not impressed at all to say the least. I can think of a better way to spend a couple hundred bucks than to find out on the dyno that you car has been neutered.
