dyno print out's?

Hi chaps
Dose my graph look right first run seemed smooth then had k100 fitted and mapped gained 13bhp but looks bit up and down to me said my manifold was restricting it?


Graph 1 befor map

graph 2 after map

have aem cold air intake, de-cat, 2.5'' b-pipe 4'' backbox

It might just be me but the images aren't working for me.

 

[speedy chris]

how about now loxy?

 

[Loxy]

Yes, working now.

He's right. You see a rise just after the VTEC crossover but then a dip in torque and power level off in the mid range. The torque would shoot up and then be almost flat if you had a decent exhaust manifold and the power would look a lot straighter.

That's the problem with the stock manifold, it's quite a bottleneck even with a decat pipe.

I can only imagine he set the VTEC crossover before the dip because the dip was worse on the low cam.

Don't get too hung up on the graph really, it's how it drives that matters.

It pulls much better and drives well, maybe keep eye out for manifold. don't want car any louder really!
