Good news/ Bad news- car made 360hp/ I have to run race gas
So my T2 FC made 360 to the wheels, but now I'm told I need to run at least 100 octane to be safe.
I have not seen the graphs yet.
The turbo is a Garret series similar to the 60-1, Tial 46mm wastegate running minimum boost of 15psi., and I'm running 720 and 1000cc inj. with FD fuel pump and aeromotive FPR.
I'm told it can't be detuned to run on pump gas and that is typical of rotaries. The boost cannot be set lower than 15.
Can I change the spring in the wastegate to lower boost?
My main concern is to keep as much power safely in the lowest rpm's possible.
I will post pic of graph when I get it.

It is a track car, but since it is licensed and insured I wanted to be able to drive it to the track, if needed. But most importantly, I just didn't want the added exspense of needing at least $135, or more, in gas everytime I go to an event.
As for lower boost, I guess the turbo is too big. The tuner says in forth gear the boost will spike, even with a lower pond wastegate spring. Not sure.
He says a racegate of 50 or 55mm would work, but costs around $500

F&L near me in long Beach quoted $45 for 5 gallon jug of 100 and $65 for 5 gallon jug of 105. That is $9 and $13 dollar per gallon. Seems like a bigger difference than pump at $3.50ish.
Hopefully I can get some better prices and I will stay race gas, and the tuner, said he can safely bump me up more hp if I stay with race gas.
The tuner is good. It is Nelson at RRR. It is currently tuned on pump, but the safety margins are too small to race with and highly recommends at least 100 oct.
We found out through tuning that apperently the motor must have a port job of some kind. when I get the graph tomorrow I will post it. Power never declined, even up to the 8200 redline. Very smooth. Tq and Hp crossed around 5200ish rpm.

I'm running Haltech E8 and the boost controller has been disabled. It is just off the Tial 46 or 48mm wastegate at 15psi.
I'm told a racegate, 50 to 55mm, will let me run on pump gas.
The car is a dedicated track car and goes places on a trailer to save tire wear, and just because I have a trailer to use. But for this first year of learning the 7 versus my SR powered 240 with all suspension mods and full cage, and gutted; I didn't want the added exspense of race gas. They are 2 different driving /handling cars.

Your tuner sound odd to me. I would check with other tuners to be safe side. I never heard tuner will tell your told to use race gas and can't be detuned, ummm idk, check with other tuners. GL

Sounds like you got a lot of things going wrong in your car mechanically also. For one the FD3S pump is NOT big enough in a lot of cases with aftermarket turbos. Something like a 1998 Toyota Supra twin turbo fuel pump generally does the trick unless you wanna go with an aftermarket unit. Also I agree with everyone that you need a new tuner, BUT in all fairness to your tuner it also sounds like you need a mechanic to go through all your mechanical mismatches or failures to make sure that the tuner has a fair chance to TUNE the car. A lot of times someone who knows more about computers and not as much about the mechanical side of the car has no idea why things are the way they are with your car. I recomend going to a shop with a lot of experience so you can get the gremlins out of your ride.
-Personally I would recomend Rotary Power in Gardena, CA. and I am sure a lot of people here will be able to point you to the right direction of other shops as well if this does not suit you. I have had my FC for the last 5 years and have had no problems with any and all the work that was done there. Well good luck and hope it alll works out!

With that being said, best/cheapest places to get 100 or 105 octane.

around 5200ish rpm.

Morisaki is right, the FD fuel pump is insufficient. Go with a Walboro fuel pump, I forgot which one tho.

I think you didnt understand your tuner. If you are gonna run your car like a dog make sure you have the recommended octane he said but if you are driving it slow to the track "NO BOOSTING" then you should be fine.
So fill her up with 91 and drive normal.

I can only go by what the tuner and builder, same shop, says. I have a haltech boost controller I was running on my BNR stage 3 turbo. 9 & 15 psi levels. Builder says this turbo will not stay below the 15lb spring in the wastegate. I specifically asked if I could lower the boost pressure with my controller and he said no.
