Default XTI-Junior tuning session

Last Monday afternoon, December 17th I was fortunate to have booked a time with Junior at PnL in Chicago to tune my new XTI build!

It's a new motor build with a MPS Long Rod 2.5 SB, HP Techs in Detroit built D25 heads; CnC, PnP'd, Hand blended, Super Tech +1mm valve train, Kelford R199B, Killer B Holy Header with custom HP Techs, SL EWG up pipe, HP Techs custom built/ Cobb FXT V-banded 3" exhaust, Tial MVR EWG v-banded custom, SuperTrapp mufflered (can you say stealth) exhaust, ETS TMIC and a Blouch 3.5XTR.

I love the sound of my XTI with the Killer B Holy headers and my EWG exhaust! Here are a couple graphs; 93 PG and E85, from my tuning session with Junior at PnL! Junior held back on some timing because of balance issues with my current 1100cc injectors. My fueling system is working well with the Walbro 400, hi amp direct wired, Aeromotive FPR @50 psi and Perrin rails. We were at 80% IDC on E85 and my Blouch 3.5XTR. I am rectifying the injector problem now and we will tweak the tune some soon!

I currently have DW 1100's older style injectors but they were new. I've got one that flows -12% off at 20 % IDC and it is causing fits at mosty lower rpm's but it's where you cruise and the hesitation stutter stuff 1500-3000 sucks big time on E85. It was not as bad on the PG but still there! DW is making good on them and giving me some new EV14 1000's so that's good but a hassle!!! Junior did not want to push it any harder with the timing as he nor do I trust the injectors. Junior's going to revise the map for the new injectors and I'll have to run a couple logs for him. I think he liked my car!

Regardless my XTI made very good power even with conservative timing! I plan to put up a thread in PPB I just don't have the time right now with the holidays, work and the new snow that I've been skiing

I hope ya'll like it!
