Talked to a tuner in a nearby city, he says utmost he can expect out of a Cobb AP tuning is around 30 hp with gen 3 intake, HFC and CBE. Thats what he got with an Uprev tuning.
I think I'm getting my car has gained about that much after installing above said parts and running pre-loaded Cobb maps.

As per board members results, some of us have gained more than that so is it worth going with this tuner or look for someone else?

 

Does this tune void any warranty?

 

since warranty is from Infiniti and you're replacing factory ECU settings with a custom settings, then Yes it does void the warranty.
Cobb does give you the option to save your factory ECU settings to revert back to.

 

30whp is a bit optimisic imo for a tune after installing those parts

 

Is that 30 HP from the tune alone, or is he saying all the bolt-ons + the tune will yield 30 HP?

 

Thats with tune and the bolt ons.

if car was at 270 rwhp with no tune and no bolt ons, it'll be around 300 with tune and bolt ons.

 

Yep 30 total, not 30 plus 30.

 

I thought he was saying his tune would net 30HP and was going to call BS.

 

I got stillen stage 3 fi cat back/fi hfc's/cobb ap with a tune I got 325whp.
staples had pulled 335whp with same combo & test pipes.
