Frequently Asked Questions

We have gathered all the most frequently asked questions, these are questions we get asked about everyday.

Q. Why is the Dynoflash reflash better?
A. Unlike the competition,  we spend more time tuning Evolutions, then we do worrying about typing articles for magazines, and we can match a mail-in flash, with your aftermarket intake. The Dynoflash reflash is a customer proven way to get great results and maintain ultimate drivability, and a higher level of safety. We can flash your car to work with your mods specifically, and our through the mail flashes are un-beatable. According to our statistics, we flashed over 650 Evolutions last year. So chances our, we have the right flash for your car!

Q. What is the turn around time for my ECU?
A. We ship the same day we receive your ECU, and we ship next day air, so you'll receive it 1 day after we received it, which is the day after you sent it to us. For a total of about 2 days. In the meantime, we will reimburse your rental car costs at the rate of 19.99 / day for an economy car. Simply let us know and fax us the bill and we'll reimburse you!

Q. Do I need a Walbro 255 fuel pump?
A. Yes and no, if you have modifications and want the max power we can provide for you, then Yes. If your keeping your car stock, and maybe just putting in a drop-in filter, then no. It really all depends on the modifications, you have and how far your planning to go. We recommend the pump on all modified cars because the stock has overheated on us more then a couple of times while tuning customers cars. Its really a one hundred dollar safeguard.

Q. If I already have a Full or Mail-in Flash, and add a Walbro 255 fuel pump, do I need a reflash?
A. Yes, we have tested this theory, and have proven that when you add a Walbro 255 fuel pump, it greatly affects your Air to Fuel Ratio, by making your car run richer. Here are some dyno sheets with A/F Ratios on them showing the conditions that adding a Walbro will do, this is why we recommend putting the pump in before the flash.

Runs 2 and 3 are our base mail flash with Stock Pump
Runs 4 and 6 are same flash with Walbro fuel pump

Q. What intakes can I use with my flash?
A. We can custom tune your car with any intake. We have most intakes available for our Mail-in Flash, those include, AEM, HKS Racing Suction Kit, Buschur, and a couple of more. We have found that the HKS Racing Suction Kit, has an overall 11 WHP gain over the K&N Drop-in filter.
