There are a million Steve's, some are even willing to do "tunes" or "touch ups" for as low as $50. They will happily talk to you all day and tell you everything you want to hear. Something I learned several years ago -- when you actually know something in this industry, you don't share it. If...

Anything over 210-220whp (which requires an RBC swap) is unrealistic. I watched a ton of these "220-230" claimed cars run 14's and trap 98 mph while at the track... 98mph == 190whp.

I provide a map with the correct map sensor setting if you tell me which one you're using (I have a notes field for mods during tune purchase). It's a simple setting and doesn't change the basemap. You can even do the same on the KW basemap, just toggle the setting from stock to 4 bar. However...

Your mechanic needs to check fuel pressure at the rail. Everything you're describing points to a mechanical issue. The one *constant* variable we have here is the base map, it's started DOZENS of cars with the same kit, same injectors, same pump, same map sensor. Your motor isn't getting enough...

I ran 11.8 with the blower, could of gone faster.

Yeah... that 3-4 hours is for me... and I've done a ton of work in this engine bay, so I know where all the odd bits and pieces are and where they go back after I'm done, lol.

One thing I didn't mention, the RBC swap is a total pain in the *** too. It moves the TB to a whole different location and the harness doesn't reach. You have to undo the big plastic clip holding all the wiring on the side of the head. Definitely a 3-4 hours shop time to do it on a customer's...

I don't reply on topics which have been beaten more than a dead horse. If I've already had my say on a topic, repeating myself is just annoying.

Skunk2 loses power over the RBC on the 9th gen.

It's hit and miss.

I shared them "years" ago...

Of course

I preferred a 13+ to save me some time on tuning. Beyond that I didn't care, since nobody stepped up, I have a local gent that is an RSX customer with a 2012 9th gen who purchased a FR DP & exhaust and is coming in for testing. He's a little closer than you are, hopefully I'll see you someday...

Full Race is better. I have a 2012 Si lined up for the test.

Back pressure is a myth and only creates a flow restriction.

LOL you guys are reading way too much into that. It's not about the car, and all about saving me some time.
