Nezil,
Sorry it was missed...I think if you go looks over my posts I noted the octane booster and content but here you go.
I was using the MMT based Lucas booster due to confirmed consistent tested results by many and not snake oil. I was running consistently aprox 7.5 oz per tank (1/2 but) and based on their formula should give a 1.5 oct bump. Now it might be slightly more since the mixing is not perfect science. Might have over 1/2 tank and put 1/2 btl in so concentration will be higher. Then also you always have the residual factor.
Anyway it never pulled timing when using it. Now I stopped using it and did some pulls and had timing pull and a couple of "knock" notations non some logs and then it got hot and the car pulls timing all over the place. Am working on upgrading to a HD intercooler to fight the IAT's. My dyno runs would start at 85 deg and top out at 150. On the road it will be at 95 on cruz then under wot it will drop a couple of deg then climb up to 130 this clean air flow.
So I have proved the booster works to control the timing pull and knock but it can't help the high IAT's. Oh and it turns your shit orange/brown, plugs, exhaust tips, 02 sensors, etc
Now i am trying the E30 map. Boost was a little low on the first pulls but I only started with 2 gal (E21). I am going up to 3 gal next. Keeping an eye on the HPFP
What gears you doing your logs in? I try to always do independent 3/4/5 then a multi shift 3-4-5 and if I don't post them all I try to reference 5th gear if I can since it puts a 1-1 load on the car and that is usually when my HPFP was crashing
Let me know if you have any other questions
