So will he be able to tune 30 psi on this blend?

[93gtpeater]

If its safe he will. You should be able to get at less 30 psi on e70. Theres alot of people running high boost on e70. Iam running 29 psi on e70 and my car is still going strong. shane will go as high you want as long its safe.

All depends on your setup and where its limits are, you won't really know juntil you start tuning. I ran 31psi on e70. Others have not been able to.

We don't really have e85 for all that long here. I'd go in for an e70 tune now and get all the bugs sorted out then head back for a real e85 touch up tune next summer. If you would want to wait until just next "spring" you will have the same issues of not having real e85 anyways.

Ok I am just going to top it off with the blend now and get it tuned. Thanks guys

The main difference in the tune is it'll be kept slightly richer so when the blend goes back in the summer it's right.
