Once again this remap thread is dissolving into the usual argument of value and substance!
To sum up, if you cant afford the custom remap you will have to get the cheaper option and get the "off the shelf" solution. There are many happy drivers/customers out there who are more than happy with the delivery and performance of the sub £400 package.
If however you can afford to get a custom remap with the EGR/DPF delete then that would be the one to go for, it is a finer, more detailed mapping process, that takes significantly more time. I hear the argument that the two products are similar but they're not in terms of labour and finished product.
I know and appreciate it takes more than a simple stainless steel pipe to remove the DPF from our cherrished cars so lets not talk the process down. I will also add that we are talking about less than a £300 difference; have you seen the price of basic engine components and labour charges if something goes wrong with the engine as a result of bad fueling etc.
Regarding the speculation that Alfatune and AHM will be reducing their prices too match is a bit premature; they have a fantastic reputation for what they specialise in, and one would guess, full order books! So it begs the question why would they?
By all means research this subject on this fantastic forum, you will find lots of opinions and recommendations some helpfull and some others!
