The amount of boost that you can run will ultimately depend on compression ratio. Getting the fuel and ignition maps dialed in will definitely help.
Tuning a car is not a matter of how many boosts you have. Being dead set on 20psI is counterproductive. Why not set your goals based on actual performance gains. 20psi may be slower than 16psi, especially if it nets you a nice hole it the block. Chances are very good that the little GTX is pushing quite a bit more air than that Chinese turbo that was on the car. Does the EVO engine management use the same O2 sensor as your wideband meter? You shouldn't run the car with a bad O2 sensor. The engine management has no way to fine tune your mixture and that's not a good thing on a setup like this. I'd make damn sure all the sensors are in good working order if you want to push this thing and you don't want an oily mess all over the firewall and bottom of your car. Every high hp BPt owner that's reading this is waiting for the inevitable boom that's about to happen if you don't tune this thing right.

Are you getting rid of yours?

YES!!

I dont actually care about the number! Thats just a ref point i have to give. I want the car to have plenty of power but be tuned somewhat safely. If i have 18 vs 20 thats fine i was just saying that i want to maximize it as much as i can.

The evo system does not use the wieband. I actually dont think the evo system reads afr. Im not sure but i dont remember having a second 02 anywhere. I think its just set to what its set to. Clearly tho i have no clue...

I am here talking about the tune because im trying to get it right! I would like to not blow it up! Its hard to know what you dont know tho. Im still learning here.

I didnt know the 02 was bad until carlos started to change the tune and the 02 showed no changes even tho i could feel the car was different. I have a new wideband i will install tonight. Then we can work on the tune some more. Maybe dial in the fuel in the upper boost levels and then i can tune the boost doen to have a safety cap so to speak.

As far as i understand you need to know the compression ratio to know what a safe level of boost is or how to tune it. Carlos shoud know what the ratio is. But 25psi might be safe for a low compression engine and 12 psi is safe for a real high compression engine everything else being the same. Thats how i understand it anyway, i could be wrong.

That sounds good to me. Im not sure which bp this motor is. I dont know what it came out of, or how many miles it has.

[Dragonhealer]

I must have missed it, what fuel are you tuning for?

[bhazard]

YES!!

I may be interested if Mike doesn't get it. Depending on your price.

The EVO system has no O2 correction? Isn't it from a Mitsubishi Evo? Even the stock Festiva management has O2 (albeit, narrow band and open loop at WOT.)
If Carlos can add that, I'd have him do it. That system should support wide band and I'd imagine that it will also autolearn. Most OEM systems newer than 1996 will autolearn.

I actually dont know much about it. My wideband does NOT hook up to the ecu tho. I dont know if i have a second 02 tho.

Your tune will need to be VERY good, even then you probably can't do 20psi even at 7:1CR unless using water/meth injection or some other neat trick. I'll bet 100% Charlie is right, your noise is detonation.

well i happen to have a trunk mount meth kit.

and now i have an evo system for lucifer. gonna get the engine bay clean after all

Don't you have corn juice over there?
Hell e85 is everywhere here . 100 low led is available down the road from me to.

[Team Lightning]

The closest E85 to me is 25 miles away at minimum and that's in South Carolina. I know of nowhere with in 50 miles of me on the Ga side that has E85
