Technosquare determined years ago that 7100 is the safe limit for first gen DE (for those that dont know, Technosqaure was the first to crack the ECU and was the only tune available for several years)...

Beyond 7100 it is advised to upgrade valve springs, oil pump and rod bolts... cams and valves have nothing to do with the safety of higher rev limiter - but can be part of helping take advantage of power in the upper end...

The reason people bump rev limiter (to safe limit) on stock internals is to max out revs and the drag strip so that you can finish the 1/4 mile in 3rd gear (shifting to 4th will fubar the entire run).


All of this is very old information, very much common knowledge to many of us that have been around a while... and have been racing and modding Gs for a while...

BTW, UpRev bumps rev limiter too... I have no idea why they wouldn't have bumped yours
