The MVPI2 is the tuning interface and software that allows you to tune the car on your own if you know how. You read the stock file and make the changes you want (on your laptop) and then load the modified tune in the car. The ngauge allows a tuning company to build a tune for you that you can...

Sticky tires first, then decide if you still need suspension mods. For power go supercharger of your choice, then your "bolt ons" will be switching to E85, pulley swaps, catless, etc. Also need sticky tires first here, a powerful car that just spins the tires is weak suace.

To be clear- meant to say long tube headers. The good performing NA cars all have the same combo - obviously sticky tires, CAI, E85 with agressive tune, and long tube headers.

Using the stock box with improved filter is my plan; however, most of the E85 bolt on 18-19' cars running high trap speeds mph's all seem to be running a jlt, steeda lid, or some CAI. They are also almost all using long tunes as well so it's hard to find real world data on stock box with panel...

There is logic built into the sw that the PCM uses that, if turned on, allow the PCM to make adjustments based on an "inferred" ethanol content in the fuel. The inferred calculation is based on what the stock wideband o2's are reading in regards to fuel trims. This process "inferred ethanol...

Thanks, very helpful info. I would not be surprised if the Lethal and Mak deletes were actually the same product

14.6 or so the stoich for 93 once the stoich for E85 was in the tune it will read 9.6 or so

It's great to see the Roush Phase 1 warranty kits performing well. Nice job.

Just as maf lb/min tidbit I was seeing 49-49.5 on my e85 tuned stock 18' this weekend, fuel trims were also less than 2%. Timing on E85 hovered around 27, with zero knock. I may try a few more degrees to test.

Gotcha, that's really disappointing. Once again, mostly positive threads on this board about these guys but the complaints are fair too when valid like yours. The lack of communication is the most disappointing, the tune itself is probably just a mistake, that is probably pretty easy to fix on...

This^ If your concerned leave it stock for a few thousand miles, most commonly a mfg defect or assembly issue will have come up by then. I think Ford probably replaced way too many motors just because the customers were so demanding about the "tick" noise. And every one of those cases (very...

Wow bro that sucks, way too long of a wait without communication on why. Im kind of confused on on why you have no tune.. What are your logs from? Anyways customer service is king and can make a business owner a king or without they might become just another pawn, Hopefully they get you taken...

Looks like the UPS man dropped some help off. Nice, getting warmer in TX too, its been too cold to hook on the street at all

Man that is by far the sweetest wheel set up on these cars

About $1.89 here in San Antonio. I'm still averaging about 17mpg overall on the E85 so no concerns on price.

I think the most popular options have been the Whipple, Procharger, and now Edelbrock kits. Any of these would be just as reliable as the Roush. Of those three I think Edelbrock has the most attractive warranty options. The reliability will be dictated by the tune and how you choose to abuse...

I'm kind on new to the S550's but I plan trying the MT SS 265/45/18's on my stock rims. The car (18' GT A10) came with the same 235/50/18 you are talking about, it was someone bearable stock but now on the E85 tune they are just spinning all the time.

This is a valid point. The 18+ roush kits are very inlet limited and have major heat soak issues. If it was a good base design, VMP would already be building kits it with it while they are developing theirs. Once you get passed the warranty worries, which are valid on a new $40K plus purchase...

Call and ask VMP, they have these combos dialed in perfectly. Im sure part of the answer will be if you are willing to add octane booster at every fill up or do you want a safer tune and pulley combo that will have a safety factor built in for pump gas that may actuallybe 91 instead of 93, etc...

The airbox will make a big difference. It's tricky to tune when fighting traction for sure. Like many, I'll be following the build. It's pretty collthat Edlebrock is so helpful.
