Well before I did the mail order tune I decided to get before numbers.
Laid down a whopping 264.7/296. This was on a DYNOmite, anyone ever had there car on one of these?
A/F was 12.5 across the board

 

Not a DYNOmite, but I'm assuming this is a device that sticks to your window and tells you HP & TQ. They are sketchy with accuracy but can be useful to determine a baseline to see how a mod affects your car.

If you have 265 before the tune and 280 after, you know you picked up 15+. But, I wouldn't use it as gospel truth. Even load bearing dynos have variables that affect true accuracy.

 

Um, no. It was on a roller just like a dynojet.

 

You should definitely be trapping faster than 106 with ported stock heads and the Crane 227 cam, BUT trapping 106 makes it clear that you're making more than 265 rwhp.
