I had this customer come back in so we could swap his forge WGA back to his blouch WGA to see if we could get the car to hold more boost. We've been having boost issues with all the Evo 10's with forge WGA and twice (3x now) have moved back to the blouch WGA and held more boost with much less WGDC.

I also ended up working with the mivec tables a bit more to make sure I had them really dialed in for the Kelford cams. Turns out I was able to eek a bit more power out of them with Mivec table tweaks.

I also ran .5 psi more on the car. Now it is running 25psi flat straight across to 8,000 rpm.

All the above made great gains on an already powerful Evo 10 MR SST on our dyno, on 91 oct. Getting close to 400whp (on 91oct) on the SST has been a target. Still a little shy but very very close.

The Dom 2.0 turbo continues to impress me, espically for pump gas performance. For a California car, it is a great upgrade that is 100% stealth.

This latest round of tweaks / tuning ended up producing:

386 whp / 336 wtq

+ 27 whp / + 20 wtq




So far the SST clutch packs are holding up. I've had to up the SST torque limit tables quite a bit to accomplish these numbers. Every 15 wtq / 15 whp gains the clutches would start opening up and slip and I would have to tweak the SST torque limit tables a little bit more. So far so good. I am actually quite impressed now with the SST trans.
