As the title really, impatience and excitement lead to me never bothering to set base timing when I fitted megasquirt 2 years ago.
I finally bothered to set base timing today and found spark to be retarded 3.5 degrees and called myself stupid. This is what I thought my spark table looked like

So with that in mind how much power is 3 degrees of timing really worth?
Its a 1.8 NB, WRX TD04, 2.5" exhaust, eBay intercooler , 20% methanol premix with 99RON. At a guess based on 111mph trap speeds at the 1/4 mile what you guys would call 270-275whp

Original boost target was 180kpa until the 5000rpm 190kpa 5000-5500 then 6000-7500 200kpa
Revised boost targets are 170kpa to 5000, 5000-5500 180kpa, 5500-6500 190kpa, 6500-7500 200kpa
Its been a long time since I did a 4th gear spool test, but IIRC it made 12psi by 3000rpm with a 5 Speed and 4.10 rear end
