id like a chip for my euro s50b30, does he do anything with those?

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.

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.

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

Hi,

I had planned to pop in here within a day or two of the initial post but was busy with work and them on Monday I got either food posiioning or a stomach flu and only recovered today. (I plan to send out the first batch of refunds on Monday or Tuesday, but I may wait till the 20th and send all the 20% discounts on the 21st)

Sure you can send the discounted price if you like, and specify which chip you want.

I will look for your email and answer it later tonight or by Monday evening.

I sent Mark an email, no reply though. Maybe my message ended up in the spam. I've answered my questions searching various forums, but I couldn't find the approx. gains.

I would also like to ask if its possible to pay (send PayPal to email) the recaclulated price?
Because the payment will go through my credit card and I don't think it can be refunded.
