Local guy here in OKC has basically the same setup stock with Autothority chips. His first dyno chart looked almost exactly like yours. He contacted Authority and sent them the chips and dyno charts. They remapped the chips for $100 (original proof of purchase required).

They tweaked the midrange and he gained like 15 peak hp and 25-30 ftlbs of torque if memory serves. We were just happy to see it wasn't going so pig rich in the midrange.

Don't know if that is a possibility with Weltmeister chips.

I have not seen anybody advertising the chips. I had to search forever just to find the performance chart. I finally found it on an individual's car page, not in an add.

Maybe Vitesse?

Yours was more that i thought that set up would give. So i am now going to seach for the k-26-8 and get some new chips . ANYONE HAVE A K26-8 FOR SALE?

K26/8 would be nice but you can do OK with
K26/6 + 3.0 bar FPR + shims + chips + 18 psi =285hp/330tq (estimated)
Mine runs nice

...but of course K26/8 would be better

people seem to lean toward the k27/6 over the k26/8, maybe consider that also. You can get your k26/6 upgraded.

It is not bugging me much, the car runs great and is plenty fast enough. If gas hits $3/gal I'll email you.
