I want to know the increase from a custom 91 octane only tune. Lots of us have no access to E85. With no bolt ons, all stock.

Price and max power is what most people will want to know I think. Lol or it could just be me. Hahahaha. I want a straight 93 octane tune.

I haven't been foruming too much lately and this is a nice surprise to see.

Good job. Very impressive. Looks like a near 300 hp single solution with a custom tune on 93. I like the comparisons with the +9 Hondata, since anyone going after this is likely already running/has run a hot basemap.

We still have not found it's absolute limit. But the delta is impressive. An easy +50 whp on pump gas is a good bump in power

You should still net some solid numbers. We have another SI this will be going on shortly that is all stock and I can share those when we get them.

Also, assuming this would be compatible with a flex fuel kit? Mostly have access to 91, but would love to try out a mix with some e85 if i got the chance!
There is no reason for a flex fuel setup to not work. Huge benefits for those that take advantage of it, especially with 27Won’s new setup.

Nice job 27Won! I’d like to see it pushed past 6500 RPM.

@[email protected] what's the possiblity of me making 300+ whp on 93? Full bolt ons.
I very much believe you can get right at 300 with 93 fully bolted and a little bit more boost. But it's important not to get hung up on the overall number as all dynos vary. It's the Delta that we are after. You are basically dropping in an extra 50+ whp with some tuning.

Also @[email protected] ... not splitting hairs with regard to part 4... but there is a statement...

"...there is not an OTS map for ethanol fuels"

...both Hondata and Ktuner (I know for sure Ktuner) have enables to have timing added based on what reading the ethanol sensor provides that you'd have to add. I have Ktuner and I have looked it over and it has a percentage ethanol content on one table to use upwards of 5 ignition advance on it's table. It's somewhat conservative as it's just a ignition bump to the basemap... but it's good for quite a bit more power. The Si dyno on KTuner's page for the Si's top curve is with the Ethanol map enabled.

Possiblity of making power passed 7k rpm? Or would I need some head work to rev that high with the added power?
