Ok hopefully not to many questions that have already been answered, but I would also like to get some input from people that have perhaps already gone this route. Ok here goes my old set up was a gt3037r, HKS 272 In/Ex with 720cc injectors on 94170008 rom. My new set is going to be PTE6262 Comp280's In/Ex and 1000cc injectors and of course no maf on intake. Now the ?'s how would you all tackle this and what suggestions do you all have I was going to install everything start by upgrading to 15 rom and hoping to scale injectors using the post that I have read since the current ones are not scaled fuel tables are outa whack to compensate. Should i go with blow through or speed density since MAF does not seem to be an option? I think I have typed way too much already and would like to see how you all would tackle this any help will be appreciated.
