if the injectors are the same you could carefully fun the same chip.the 62 will move alot more air than a 44 so you will need more fuel if your going to push the boost.you could go into the chip and add fuel up to 20% and look at the afrLastly......I had a TE44..will I need a new TT chip burnt for this. I emailed Eric, but have not heard. Everything will stay the same, except turbo?
