Part 2 :

After mods were installed, no PCM calibrations made shows these mods cannot be used on their own for LTFTs were quite lean by 11% so tune 1 was required and here is the results:



20 mile test drive, PCM being recorded, no performnace gain, less torque :



Via PCM tuning, only MAF table used to reduce the 11% lean problem, 2nd tune, LTFYs close to zero, Over 500 knocks in just 20 miles ! :



2nd PCM tune, even though LTFTS was MAF table tuned to average around zero, had to adjust injector flow to solve high knock count :



HP and torque after knock was taken out :



Bottom line, after much work to make the mods fit, tune the PCM, the performance is no better then before the high cost of these modes.



I'll do further testing but all I see is the PCM calibration had to be done differently then before these mods but gave no positives at all to spend that kind of money which I assume would be about $600 dollars plus another $600 to have PCM custom tuned, thus a $1200 no performance gain.
