Today I went over to Hi Tech Motorsport for a Dyno test & rolling road tune i.e. fuel pressure and ignition timing optimised. Yes the gear he uses is old, however my engine is old too.
Been here a total of 4 time now and each time I could not fault the readings. Then with the NPOC (G20 chassis) chaps DE’s with I/E/H made around 135 – 140whp the same over the UK for same tuned SR20DE’s

not quite the 200bhp mark, its 196bhp @ 6400rpm with ignition timing set to 19* and fueling set to 4bar. It was 192bhp @ 17* ignition advance, however at 19 there gains everywhere.
