Acceleration tests don't tell the whole story especially on the good old highway ulube, two years ago we tested my stage 2 roc (200ps one) against Revos stage 1 GTI at Brunters and was in the mid range where it really showed I'll have to try and dig out the figures as the were Vbox
I know Revo are benchmarking stock, stage 1 and stage 2 performance on their demo car at the moment
Oddly I've never found any of the Stage 1 maps I've tried from the big three that linear give all give you the surge of torque, the rocco was far better as a stage 2 car but trade off was zorst and intake noise so it ceased to discreet, the IHI was cracking as a fast road car given the lack of lag compared to a K04 car but always left me wanting more at the top end
I ran with intake and zorst for a while and stage 1 and only noticed the difference when we went to stage 2 as the stage 1 map is not optimised for the hardware
I totally get why people stick at Stage 1, our Pirelli is Stage 1 and will remain as its a great daily, sold the roc running the 95 Ron Revo stage 1 and was a nice set up
