go with a chip, the mafterburner only changes the MAF signal... it cannot change timing, codes, rev limiters, fan temp or anything like that...
id just get a JMS chip with some different tunes for race fuel and such... then when you get the blower you can have different boost settings and such as well...
the mafterburner is good only for fuel, and besides if the chip is done right, you'll never have to touch it again...
you could ruin your car with one wrong click of the mafterburner..... not to say you couldnt do the prgram yourself.....but think if you overlooked something :o BOOM!
