I run my dc2 gsr in a DSP class. The rules permit portmatching, milling the head, adj cam gears and unlimited intake possibilities . I have a gsr itb setup,I plan on portmatching and milling, but is it worth it to get the adjustable cam gears with stock cams? I have read that the stock injectors will be ok (240's). The itb's utilize the stock map,tps and intake air temp sensor. What program is the best for this? Hondata, crome, neptune, others? Thanks in advance.

anything that can tune itbs, which is goni to be hondata, crome pro, or neptune.

 

Even with stock cams, there are benefits to be derived from cam gear tuning.
With ITB's, the best option for tuning is any program that offers TPS based maps. The Hondata S300, the AEM EMS, and even Crome all offer TPS based maps.

thanks for the info

 

If you mill the head you're definitely going to want the cam gears to put the cam back to straight up. To get the most adjust the gears on a dyno and figure out where is make the best power for your application.

 

in that class arent u only allowed to port 1 inch into the head and 1 inch into the manifold or tps? isnt iit like hc?

 

Crome Pro did just fine tuning ITB's and will be your cheapest option that supports ITB's
