A good tune can be recognized from the graph and this tune follows that. Hopefully the final tune will be even better.

 

We have now completed our header tune and are very happy with the results. And dyno results aside (+20hp), the car drives so much better its really a big difference you can feel. Engine genuinely feels much more responsive and revs faster. As you can see, the power stays up all the way past the stock 6800 rev limit and keeps pulling all the way up to our recommended maximum rev limit of 7200rpm... that makes a big difference as far as the "Area Under the Curve" which is even more important than just the peak power reading.

The dyno results below are for stock intake box with AFe drop in filter. With the exhaust and tune, we did not see any gains with an intake (which is why we do not sell one currently), but but with the headers, we feel there will be gains with a good intake, so we are currently experimenting with several options and will report the results once complete.

Dyno results below are for AWD IS350 F-Sport. So a similarly tuned and header equiped IS350 should be in the 300whp range.

 

if a group buy is inevitable, can we at least get a name list going?

 

Here is another plot showing total gains VS stock IS300 and IS350.

+44whp gains for the IS/RC/GS350... and a crazy +70hp on the IS/RC300!

We are updating the website now, will have complete power package pricing with PPE Headers and ARK Exhaust (we have a large inventory of ARK Performance Exhausts in stock):

 

I'm good for a group buy...looking to purchase within 4 wks time...lets see if we can get something started

 

I've asked him if we are good and when it can start, but he hasn't responded yet.

 

I would like to see a dyno run with just the headers, not the tune. If 35 HP is from the headers and 5 HP from the tune it is a pretty expensive 5 HP.

 

interested in a group buy as well for the is350 rwd.

 

Hey all, so regarding a group buy, we are hold off on that for two reasons:

(1) Currently the OBD programmer is already discounted $50
(2) We have gotten requests for package pricing with exhaust and/or headers. So we now stock ARK exhaust and Invidia also, as well as PPE headers. We just posted our package pricing as options when purchasing the tune. So there is even more savings there.

We will run our sale pricing on the tune through March, after that we may do a group buy later in the spring.

Sorry about that, right now we want to hold off on any GB's. We are also working on our own exhaust, so that will also be a reason for us to do a GB in the future.

That's vert disappointing to hear, We have 10-15 people wanting a group buy now.

 

I'm really sorry about that. We will do a GB later, but not together with the introductory price.

So yesterday I went to the drag race in Riyadh, Saudi Arabia my car set up is ( FBO + RR Tune ).

I took the second place on NA race. This is one of the videos my car VS Challenger R/T Full bolts-on + Tune. i won this run


Will upload more videos in my channel soon

 

Do you mean RWD is350?

 

So the headers gain 20 whp over the tuned with a catback?

 

No, these results are AWD, so due to the HP loss of the AWD, they are about 10-15hp less than RWD.

Yes, Tune + full exhaust makes about 20hp less than Tune+Exhaust+Headers.
