Will generally Not like as much boost on 98 but e85 happy days

using the Perth-WRX mobile app

All parts were for an 8:2:1 comp ratio...
Need to get the final reading but it will be at 8.2 or just out by a bee's dick

As long as you have a competent tuner i think you can get away with running a slightly higher comp ratio.

8.2:1 wpuld make it the same as factory, for some reason i though i read it was running slightly higher than stock. Guess it is all the extra headwork and the freshness that giving it the extra punch then.

Exactly what I've been saying from the start, its the headwork
Did you notice my idle vacuum reading? 11-12 lol

My 207 idles with 10-12inhg.....That's pretty normal for a cammed motor, stock cams pull more vacuum at idle because they have less valve overlap.

The improved response is due to cams as well, the motor is now breathing easier (with more valve lift & duration).

I'm running 8.4:1 in mine.

Looking forward to your seeing the results of your final tune dude
