Well after repairing some ridiculously bad workmanship from another local workshop and apparent BMW specialist we have some results with a customers 335i. Car has CP-E dumps, intercooler, AFE intake and BOV and RB turbo's with a JB4. After numerous issues from the original fitment and with some help from Terry and the boys we have a pleasant result using the BimmerBoost software. Map 2 on the JB4 saw 412hp and map 5 428hp, these figures are on our dyno dynamics chassis dyno whith is brutally honest. A stock car makes around 250hp for reference, a dyno after all is just a tuning tool not the ultimate word in horsepower.
