so your street tune and his street tune were at 9.5 psi? What boost was for the 162 whp tune?

Internal wastegate is when the wastegate is inside the turbo. External is when you mount a separate wastegate outside the turbo.

Yes both tunes are at 9.5psi. Only differences between the whp apparently are the maps themselves. He did suggest that 9.5 is a bit high for a dd so when I do the exhaust modifications I will most likely lower it or put an electronic wastegate actuator.

And I'd just like to clarify about the tunes, I wrote it kinda messed up, he gave me 2 professional tunes, one for street and one for track. I also have My own personal street tune but I will never be using that again. Just incase there was some confusion between the dyno'd street tune and mmy street tune.

Still confused about the "track" tune. What was different about it to gain the hp?

^ It didn't sound like they drained the tank and put in different gas for this tuning.

Naw was same fuel, same everything. Nothing was changed except within the tuning parameters.

Only thing I really know about it is its not recomended by the tuner to run on a daily basis and it throws a engine code and my afr's are mostly richer. I guess the same way he tweeked out the extra hp from my own tune; he tweeked out a few extra hp from his own tune but feels its not as safe as his previous tune.

Richer would make less power, not more.

yea. I would think that he means on the edge of lean hints the expression, "leaner is meaner" going on the rich side would be safer.

something sounds off with how your tuner does business, no offense, but it makes no sense whatsoever to think that it is safe or that there are different curves for the same octane rating fuel....sounds a bit odd to me.

^man dont start putting that in my head..... Also I'm running 91 octane.

Sorry guys I don't have much info about the tuning difference. I also wouldn't recommend the tuner as my afr's still fluctuate quite a bit.

Like said before, only thing I know is if I run the track tune I get system rich (afrs at 13.5ish cruise and about 12.2-12.5 wot) street tune I'm running 14.2-14.7 cruise and 12.5-12.8 wot

I plan to get a new exhaust with less restriction and get a retune so will most likely be getting it done at a different shop

Don't expect solid AFR's when tuning with the FIC. The onboard map sensor has no buffering, so even though you may be 7psi at wot from 3000rpm till redline (example) ... the map sensor rarely traces that.

Also, don't hassle between 2 maps. It just makes things more complicated. I have one map, lower boost levels are safe to run without meth injection. If I set my boost controller for over 20psi, that part of the map is optimized for meth injection. Over 27psi, the map will be optimized for race gas (have not done so yet).

With water/meth and raised boost on stock engine,has anyone been able to find the max power that can be safely made?

Most boosted engines [1nz fe] are rated at 180bhp. So am i right in saying that no matter water/meth or boost raise then is 180bhp all we can extract from the stock 1nzfe?

I wouldn't take it past 180whp with stock rods and pistons. Mine bent a rod two days after dyno run when I put out 197whp. It was a cool day and the car was just ripping fast. I guess a little to much boost at 12psi. I am still surprised it handled so much for so long. I drove at 10psi for a year with no problems. I ran 11.5/1 afr at wide open.

I also ran 10 psi for a very long time before one of my injectors clogged up. Just my luck. Got me 203whp tho. Just make sure you are tuned really good.

Agreed with the last two posts, but where do these "ratings" come from?
