My tuner said my timing is 12 on one bar of boost. 

But your running 1.6 bar of boost, is it still 12 degrees of timing at 1.6 bar of boost?

Also, is there e85 fuel at the petrol stations in Dubai?

Timing map only tells part of the story, I've seen a few cars where the CAS has been adjusted so you might see 12 at the ECU but at the motor you could be seeing 8 kind of thing.

A S15 I converted from PowerFC to Nistune had just that, CAS was turned back to have less timing than the ignition map itself lol... "Choonered".

Seems bang on to me , g30-900 will make 900 crank on e85(on paper). Deduct ~25% for 98 and you are at 675 crank. Run that to the wheels and fact you are only running 26psi you end up about your number. 

People forget how magic E85 is now that just about everyone is running it.  

"Back in the day" you had to be north of 30psi on a 850+hp turbo to get 600 at the wheels on 98.

He didn’t provide that info to me but I think I’m on standard timing. And no we don’t have e85 on the petrol stations here but it’s widely available here from shops. I’m just planning on getting a better ecu before switching to e85

That's fair enough. 

Might be time to just enjoy what you have until you sort the ecu/flex sensor situation. You can pretty much guarantee that you are knock limited and e85 is going to be the solution to more power.

Yeah I think overall I’m running the expected power I should be running for now and I’ll just enjoy it for the time being until I get some other parts. Thanks for the advice mate I appreciate it!
