Question Cold air intake worth it with ECUtek?

I currently have a K&N panel filter, UR pulley kit, Stone Racing headers, BPM twin dump dp, high flow cat, 3" exhaust and a "best guess" Vishnu ECUtek w/ the stock boost map.

I have to keep the stock boost map for SCCA STX class.

I plan to get the car dyno tuned and the ECUtek tuned for the car in the next month, as the car is running a tad lean on the lower end of the RPM range and pulling back timing a tad.

Should I pick up a CAI before I get the car dyno tuned? Will I see any more gains by adding a CAI to the current set of modifications provided I keep the stock boost levels?

I know shiv is against CAIs, but I think I have seen him post that they will add HP if the car is tuned for it.

You should clean your maf sensor and put in a brand new stock filter. K&N's suck.

Dont go with a CAI unless the tuner your going to use has actually tuned 'around' the one that youre going to go with. If he hasnt, youre in for worse performance than stock.

I say stay stock, keep fresh filters in there and enjoy the factory CAI.

The cold air intake will see a little horsepower increase. Is it worth the time and effort, I would say no. As for tuning them any good tuner can tune ANY cold air intake? We have been able to tune anyone that is put in front of us in a no time.

If you do not tune for the CAI you can run rough depending on wether the the CAI is identical to the stock one or not. Most of them are not and you need to retune for them.

All I'm looking for is a *little* HP increase. We are pretty limited to modifications in STX class and I have pretty much everything except an intake and dyno tune taken care of.

Considering I was 2nd place at the last event by 0.040, the time and effort for 5whp would be worth it for me

Thanks
