Not Happy, Stock Results

Very normal. Don't worry.

 

Here's my best stock run on a hot day...it got as bad as 340hp. I'm sure if you looked, your AFR would have been way low. When the motor gets hot, the ECU dumps fuel to keep the cats cool. Drops performance dramtically. The motor runs best in the 60s and 70s. Dyno runs should be done quickly and with a cool engine.

Did you put the coil pack covers back on? That makes a big difference on the dyno.

 

 

Really? Has this been the experience of many others? Now I'm wondering what my numbers might have been- they were left off yesterday during my dyno...
