I think for known and tested mods it may be ok but how can he map for every eventuality without getting the positive calibrating feedback from and physical dyno?
When getting dyno pulls he asks that you do Full throttle pulls in 3rd gear on a flat road I suppose this is a bit like getting dyno pulls on a dyno. To be honest MJ it really is up to you what way you go with your tuning but as said by a few of us on here, he really is an amazing tuner and worth using for £120 also he still doesn't disagree that using a dyno isn't good but he can setup the car without it and with it.
Here what he does when using him to tune ur car
Type R - the ultimate tune
This tune includes a complete Wide Open Throttle (WOT) analysis and tune as well as a complete part throttle and knock analysis package. The WOT portion is similar to what is done at a dyno shop except with more revisions while the part throttle tuning is focused on zeroing Short Term Fuel Trims (STFT) which will not only improve WOT transitions but also inturn improve throttle response, performance, low end torque and fuel mileage.
Detailed list of items:
Includes Part throttle analysis
All Volumetric Efficiency tables analyzed and revised for all degrees and levels of vacuum
Short Term Fuel Trims analysis and smoothing
Knock table analysis and revision
Ignition analysis and revision
Lambda Overlay’s and Cam angle High/Low fueling
Cam Angles High and Low
Ignition Tables for all degrees
VE Tables analysis (WOT - MAP/SD) or MAF Cal Analysis (AFM)
Throttle Table analysis or revision for larger TB’s
VTEC Point is checked and revised based on Flow/Performance
VTEC Window + Pressure analysis and revision
WOT fueling and knock check.
Limiter Tables checked for errors and safety margins
Cold Start fueling and IAT graphing checked/revised if necessary.
Overview of potential errors or engine codes if present
Choice of Race (small margins) or Performance Map (enhanced margins)
Includes Re-tuning for 30 days
Includes Forced Induction Packages as well.
