My 270 odd engine uses a 68mm Skunk 2 Pro throttle body port matched to a ATR IM.

As previously said, tuning ITB seems to be very hard, alphaN management need an extremely good accuracy to obtain good results

You also have the possibility to use ITB with variable lenght, with that you would obtain the better results all over the rpm range, but it is more difficult to correctly adjust the engine management system ...

So keeping an intake manifold is the "common good sense" option

You should see early 240's and early 170's torq with a decent exhaust system.

My ATR has been tuned and i only have 220hp

But it is a crappy tune, emissions are extremely bad, idle was at 1000 rpm,... i hope i'll obtain better numbers when i"ll tune my engine myself

I'm running an ATR lump with full Mugen exhaust S2k injectors and Type-S intake. Tuned on an AEM EMS making 242bhp and 172lbft.

STK prelude has a very similar build and only making 1bhp less.

You are Lucky guys !

Here in France, there's no real good tuner for the H22 engine

I'm looking for one of those "240bhp" map to see where is the difference between my map and yours

, but it is hard to obtain one .

I understand that if you pay for something, you won't give it for free, and generally the tuners didn't like to see their maps given for free, so i hope i'll obtain one of these map to compare it , maybe one day i will be Lucky

240 bhp is a ver good number, you must be very happy of your engine

edit: I also have a decat, a Mongoose exhaust, S2K injectors , OEM ATR intake with a K&N air filter panel and 64mm throttle body.
