Just wondering if those 3 mods would be a bit to much for Cobb's stage 2 map with the HKS drop in map (using green filter though)? I would eventually get an over the net tune with someone, but for a while would it be ok?

 

Ask Mellon, Ask Cobb.

 

well yeah, that's why I put it on a forum... so Cobb could tell me. Mellon can't tell me... he's a custom tuner and unless he looks over the stage 2 map.

 

i heard the UICP you will have no problems....search for UICP and you'll see a few threads come up in regards to the cobb AP

 

I'm running this similar setup with no issues.

 

In my VIII, I am running the stg 2 mods + uicp and licp. It does not effect drivability at all, but I am not getting the full benefit from the parts without a custom tune.

 

Every engine and induction system is different as you already know... seriously just invest in a wideband so you don't have to worry.

Timing maps on the COBB stage 2 tune are fairly conservative IIRC, so just make sure the AFR's are OK. It would only take 1 dyno tuning session to confirm, so do that *shrugs*

 

I don't know of any decent tuner in my area that can do this

 

any Cobb guys out there that can give me an answer? Perhaps with the new ATR software will be easier to work with so I can do a little fine tuning myself?

 

yes it would be fine. I ran the same, no issues, runs rich for me (10.9-11.0 AFRs) YMMV.

 

ymmv?

 

your mileage may vary

 

I ran this setup all last year with no issues, but I didn't run the revised map for the HKS filter. It was a little rich for me, so I just ran the standard Cobb Stage 2.

 

I ran a similar setup (tested with both Cobb SFI and AEM intake using the proper maps for each) for a while and the only thing that I noticed with the Nisei UICP is that peak boost did increase about 1psi which took me from 26psi to 27psi spike at WOT. It only lasted a fraction of a second but it still made me nervous. Didn't have anything except the Cobb at that point for datalogging so I can't tell you much more than the impact it had on boost.
