I've gone from Stock to Dinan to Wolf, nothing to write home about. Certainly no 10% gain in power... that'd be nearly 30hp on a stock M70, around 24rwhp. I swear the Dinans felt like a restickered stock chip... meaning nothing.

Also, these cars were okay to burn 87, if the timing hasn't been changed what's the point? All the power lies in the timing curve. I added 6° to the curve on my F150 and gained 16rwhp alone WITHOUT touching the air/fuel curve. Leaning out my A/F down low would help these cars down low too. The low compression of the M70 gives up very little power. Around 2.5% of total output per full point of static compression.

I'd love to be able to tune my 156 ECU myself. Then once I get it maxed out on 93 pump I'd share the tables with all. I can safely say there is far more available in this motor than these "chip makers" are letting out/selling. All the maps entail are 3D grids dependent on load and RPM. Smooth them and rescale, not difficult.

Same with the transmission recal chip, if I had one I'd read it and upload it to a server for download by all to reflash.



I'll send money if you wanna dyno test the three. It's around $100 for three pulls down here.
