Is there going to be a group buy on this anytime soon or is anyone selling a used copy ??
We aren't offering a discount on this book for group buys. The book is $69.99 and it's a bargain! What other book provides case studies that show you exacly how to tune EFI systems using a specific and detailed process? This is the only book that shows you how to tune step-by-step, and how the process is applied in the real world. The book includes dyno graphs which show the results and exactly how much power each step of the tuning process picked up for EACH CASE STUDY, as will as useful tricks and tips. This is why we have so much trouble keeping the book in stock. It's our best selling product! There are cheaper "tuning books" out there, but none that delivers the goods the way the case studies in MASTER EFI TUNER does.
Also, in the not-too-distant future, we'll be offering EFI Tuning classes at our new location in Boca Raton. When it comes to tuning EFI, we here at Masport Speed Shop are doing everything we can to put you in full control of your own engine. If you're ready to take control, go to www.masportspeedshop.com to buy the book. You won't regret it!
