How Do You Get 350BHP from a 1.6?

I'm certainly not familiar with your setup, but your timing map could definitely use some work.
Take a look at: https://www.miataturbo.net/attachmen...1&d=1310313155, quite a few people post their timing maps. You can look for a similar setup and get an idea where your map is conservative. Also have to take fuel into consideration, not sure how UK fuel compares to US fuel.

Fuel is 95 Ron to 98ron for super unleaded. I thought there would be scope to adjust. I'm slightly concerned that changing my settings to someone elses may imPact the reliability of my car. I know mine is running rich and I knew straight away that the guy didn't get anywhere near what it should be out if the car.
I will copy a setup of someone similar and see if there is any noticeable difference. I suppose it goes back to the original question on reliability on standard internals and making sure I don't over do the standard internals

Are you registered on Mx5Nutz.com RonnieBiggs?
Recently we were talking about tuners in different parts of the country, I think you should try and find someone that knows what they are doing.
There isnt a huge amount of specialist around darlington (maybe some in Newcastle)
There are some if you venture down towards South Yorkshire.
Well its about $1 per litre more expensive

Yes I'm on nutz. I put a post on there ages ago about ms tuners in the north east. I would drive to south Yorkshire if it meant getting a good job done and going an extra 100 bhp.

Re. fuel: I looked this up a while ago...
Our UK RON is roughly equivalent to US (MON?) fuel + 4.
So - our standard is 95, equivalent to US 91.
'Super unleaded' in the UK is usually 97 or 98 and is available nearly everywhere that 95 is available. So that's like your 94 in the US.
Tesco sell 99, and there are Tesco supermarkets all over the place. So that's like 95 in the US.
Super unleaded here is currently priced at 9.1 dollars per US gallon. You've got to REALLY like cars over here, ha.

Yeah, except not where it matters (WOT+full boost). That's about what I would expect to see on pump gas with a T28.
Are you plumbed through a stock cat or something? Are you sure the dyno doesn't read low?
Your "tuner" is a hack, BTW. Never go back there.

I've gone onto cops now and at some point I'm sure I will figure out my ebc problem so that should be working. This along with trying to improve the tables will hopefully get me some decent power increases. But if I only gain 20bhp that's still only 260bhp running 17psi on a t28 turbo. No cat fitted. Any other suggestions?
Obviously first sort tables, then ebc

What are the turbo specs? The old T28s were just 2560Rs, weren't they? Big difference between an old T28 and a more recent aftermarket GT2860RS/2871R.
What do stock Miatas make on that dyno?
