But once that boost kicks in its all up from there right? im running it now but the car is defo not remapped for it kicks in around 3k at the mo.
Also here is a n00b Question for you - why does the Rev limiter hit at 7k but the Red shows up to 9k?

lol think i need to spend less time on this forum, makes me a paranoid wreak lol!
i swear every little noise i notice i panic these days lol,
have an induction kit on and in the higher gears in boost you hear the boost presure but because of these forums i now think there is a boost leak!
and because my coolant went down abit over 1000 miles i think my head gasket is gone lol!
So yeah guys next time how about
"in the high 300's with a little bit of lag"
lol

When you say kicking in? I have a vf24 and mapped it, it is hitting 11psi at 3k and the full requested 18psi just before 3400, I cant imagine a vf22 being any less than 400-500 revs higher than that, which to me is laggy.

try shifting from 5th to 2nd at 90mph, youll see it wind all the way round! hahaha.

My VF22 is currently making 313/365 @ 1.4Bar with no issues at all, and it could have gone more but i didnt want to push anything to its limits at the time. This is on a 2.5 not a 2.0 and it has hardly any lag

Heres some info i found on another site.....
This info is a great help and answers a mass of turbo questions on power and capabilities
IHI turbo.
The VF series (VF22, VF23, VF24, VF29, VF30) are the most common direct replacement turbos. All VF-series turbochargers use the same roller bearing, water-cooled core assembly. The differences are in their wheels and housings to achieve different flows.
The VF22 has the largest potential for peak horsepower. In other words, in the IHI model range, the VF 22 supports the highes boost levels. It is capable of running up to 25 psi. Because it is a roller bearing turbo, turbo lag is minimal...the boost comes on around 3300 rpm. Expect to max out the VF22 somewhere in the 400-450 hp range.
The VF23 starts the middle ground. It comes on boost around 3100 rpm and is capable of running 20 psi of boost. Expect to max out the VF23 somewhere in the 300-350 hp range.
The VF 24 starts to come on around 2900 rpm and will significantly improve power through the midrange over the stock TD04 turbo. However, the VF 24 is only capable of running around 17 psi.
The VF23 and VF 24 are a great replacement for those who value drivability higher than maximum power.
The VF29 & VF30 delivers a very wide increase in torque over the standard TD-series turbos. It is important to note that the VF30 is not a roller bearing turbo.
----------------------------------------------------------------------------------------------------
VF22
This turbo has the highest output potential of all of the IHI VF series turbos and is the best choice for those who are looking for loads of top end power. The top end power however, does not come without a cost. The VF22 spools significantly slower than the rest of the IHI models due to the larger P20 exhaust housing and is much less suited for daily driving than some of the other models. Although the largest VF series turbo, the VF22 is not quite optimal for stroked engines or those who wish to run more than 20PSI of boost.
VF23
This turbo is considered a great all-around turbo. Like the VF22 it utilizes the largest P20 exhaust housing. This housing is mated with a smaller compressor housing of the of the VF24. This turbo is considered optimal in applications with range from mild to slightly wild. It does not have the same top end power of the VF22, but spools up significantly quicker.
VF24
This turbo shares its compressor housing with the VF23 however, this housing is mated with a smaller (P18) exhaust side. The smaller characteristics of this turbo allow it to provide ample bottom end power and quick spool. This turbo is very popular for Imprezas with automatic transmissions and Group N rally cars.
VF28
This turbo came standard on the STi Version 5. In terms of overall size, it is smaller than the VF22, VF30 and VF34, and about same size as the VF23.
VF29
This Turbo is nearly identical to the VF24, with the same compressor and exhaust housings. However the compressor wheel in the VF29 is has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such this unit is typically chosen over the VF24.
VF30
The VF30 is commonly considered the best bang for the buck turbo in the IHI VF series line. A relatively new model the VF30 features the same exhaust housing as the VF24 but a larger compressor side similar to the VF22. The combination of these two parts results in increased output potential without the lag associated with the VF22. Although it doesn't offer the top end supremacy of the VF22, the VF30 is a great compromise between these unit and the quicker spooling models.
VF34
The VF34 is nearly identical to the VF30, with the same exhaust housing and compressor. However the VF34 goes back to the ball bearing design, and in doing so achieves full boost approximately 500RPM sooner than the comparable VF30. The VF34 is the most recent IHI design and as such costs slightly more than its counterpart. Top end performance and maximum output are identical to the 30.
VF35
VF35 The VF35 has identical internals as the VF30 and it uses divided thrust bearings. However, the exhaust housing is a P15 which means this turbo will have fantastic spool characteristics. This turbo is standard on the new WRX Type RA. LIMITED SUPPLY.
more info
VF36
Roller bearing version of the twin scroll VF37, also has a titanium turbine and shaft for even quicker spool. Same compressor housing as VF30/34, however twin scroll P25 exhaust housing provides slightly better top end output due to reduced exhaust pulse interference. This turbo is good for 400HP and used on JDM STI Spec C from 2003 onwards.
VF37 (thrust bearing)
Enter the age of twin scroll IHI turbos. Same compressor housing as VF30/34, however has a new twin scroll P25 exhaust housing that provides slightly better top end output due to reduced exhaust pulse interference. Twin scroll also provides better spool up for improved low down response over the VF30/34. This turbo is good for 400HP and used on JDM STI from 2003 onwards.

From: 1600cc's of twin scroll fun :)
Don't go by the figures given off that yank site, their version of hp differs completely to ours, the examples being the vf22 and vf36 figures which are totally incorrect.
Op, the vf22 is a laggy beast especially compared to modern turbos, it's also pretty fragile and doesn't like too much boost.
Far better turbos out there.
