1.8 rockers are holding you back. No matter how much those other guys are telling you to keep them on, the sooner you take them off the better. I'd take Tonys advice. Based off of what I've seen from everyone running 1.8 rockers, their #'s are less than stellar but when they switched back to stock 1.7's they picked up the "lost power"

I would have to agree with Vinci on the rockers. Can you email your tune? Do you have any logs to peruse?

If the rockers are causing an issue, it should show on the dyno. Do you have one to post? Also, which AFR springs are you running? I had some issues with the 1.8's that were valve spring related, but it was very evident on the dyno.

One other option if there is another around, is to put it up on another dyno for reference.

I will be meeting someone next week, and if you want I can send you my tune.

How do you figure? Bolt-on M6 cars make that much torque (or at least mine did). Seem low for a 6 speed with all those mods.

Talk about a 'safe' tune...that air/fuel ratio is ludicrously rich.

I just looked at my cam curve, Vinci 056. I think your tune needs some work as your curve seems really low in the lower RPM's even compared to mine, and mine is 216/225 on the duration.

You think it will be worth my while to get in touch with my tuner about tweeking the tune a bit?

yes. 11:1 is very rich. need to be in the 13:1 range.

Definitely.

Based on my curve in comparison to yours, I think there is a lot left on the table. If you trust the tuner, go back. If not, find someone else.
