^. At one point Mark was doing work out of a shop in Rochester for custome tuning. I'm sure he will respond shortly.

Mark,
Do you know the power gains of an M20 with your chip and 19lb injectors vs. an m20 with your chip and stock injectors?
thanks
-Craig

The gains are not much, and I don't feel that the original 14# injectors are undersized. Changing to 19# is popular because they are cheap since they are used in Mustangs, but if you upgrade, 17# is more than sufficient. I tuned the one chip for 18# injectors so you can use either 17 or 19# ones with it.

You don't need bigger injectors unless you modify the motor to increase the VE. If you don't, it's not breathing more air and so added fuel is not beneficial.

Hi, yes I tuned a s50 chips but have to locate the dyno runs if that's what you are after. The results are very good. I also tuned s50b32 motors on that same dyno and got 240 hp at the wheels with one of those.

Summary: I have chips for the s50 US b30 and b32. They cost $285 and are eligible for the discount.

I have made chips for the Euro s50b30 but am not interested in selling those, mainly because I can't guarantee you will be happy with them. You need to run 94 octane to get much extra torque from them, and those motors are pretty stressed as they are, plus many that I have seen are in need of a rebuild and for that reason, the results after chipping are all over the map.

Damn, every day late is a two-dollar thirty short... devious

Today you would get 19% which is still awesome.

Ahh im torn between a Mark D and Miller MAF
It seems Ill get more power gains with Miller MAF and its more guaranteed

[Wh33lhop]

I'm curious about this too. I'll email him if you haven't already.

I emailed Mark, no response yet. I'm going to order an M50NV chip, just awaiting his response and, admittedly, some funds (ugh).

[Wh33lhop]

Order placed; can't wait. :up:

Edit: ugh. Forgot the damn coupon code. Sent an email, but making a note just in case he checks here first.

Payment sent a few days ago, can't wait.
Though I'll have to wait a couple months till the damn weather gets better.

Bah, more power is still fun with no traction. :p

damn, what do you suggest then? I need a chip to delete my EWS anyway, so one that can bump power would be nice.

I can run 98 ron which is i believe 95 right?

Very much so. Problem is I hate doing anything when it's under 15°C outside, even swapping light bulbs.
Though maybe I will install it soon after it arrives because I know I'd have an itch to try it. I've already found a second ECU so I can swap whenever needed.
If the roads stay dry I also want to do some amateur tests with each ECU.

Sorry I was working too many hours on my other contract job. I did receive your order and will look at your email again if you still need an answer.

I just started sending back refunds a few hours ago, and still have many to send out.
